DONALD  TRUMP WILL ALWAYS FIND A WAY TO BLAME SOMEONE ELSE FOR ANYTHING AND EVERYTHING.  EVEN IF A MILLION PROFESSORS OFFERED PROOF OF SOMETHING, HE WOULD DENY IT. 
  
  TRUMP WAS  TRAINED BY ROY COHN TO ALWAYS DENY, NEVER TO ADMIT HIS GUILT UNDER ANY CIRCUMSTANCES. ALWAYS DIVERT, BLAME SOMEONE ELSE. NO MATTER WHAT HAPPENS,  DONALD TRUMP WILL LIE. AND STILL, MILLIONS OF AMERICANS SAY, "THAT'S  OKAY." WHY? 
  
  IF YOU TELL A LIE LOUDLY ENOUGH, OFTEN ENOUGH, THE PEOPLE WILL BELIEVE YOU.

        What Donald  Trump Learned From Joseph McCarthy's Right-Hand Man
        Mr. Cohn made  his reputation as a prosecutor in the Rosenberg espionage case and as an aide  to Senator Joseph McCarthy, was Mr. Trump's lawyer for 13 years. 
  
  
        The future  Mrs. Donald J. Trump was puzzled.
  
  
        She had  been summoned to a lunch meeting with her husband-to-be and his lawyer to  review a prenuptial agreement. It required that, should the couple split, she  return everything - cars, furs, rings - that Mr. Trump might give her during  their marriage.
         
        Sensing her  sorrow, Mr. Trump apologized, Ivana Trump later testified in a divorce  deposition. He said it was his lawyer's idea.
         
        "It is just  one of those Roy Cohn numbers," Mr. Trump told her.
         
        The year  was 1977, and Mr. Cohn's reputation was well established. He had been Senator  Joseph McCarthy's Red-baiting consigliere. He had helped send the Rosenbergs to  the electric chair for spying and elect Richard M. Nixon president.
         
        Then New  York's most feared lawyer, Mr. Cohn had a client list that ran the gamut from  the disreputable to the quasi-reputable: Anthony (Fat Tony) Salerno, Claus von  Bulow, George Steinbrenner.
         
        But there  was one client who occupied a special place in Roy Cohn's famously cold heart:  Donald J. Trump.
        
    For Mr. Cohn, who died of AIDS in 1986, weeks after being disbarred for  flagrant ethical violations, Mr. Trump was something of a final project. If  Fred Trump got his son's career started, bringing him into the family business  of middle-class rentals in Brooklyn and Queens, Mr. Cohn ushered him across the  river and into Manhattan, introducing him to the social and political elite  while ferociously defending him against a growing list of enemies.
         
        Decades  later, Mr. Cohn's influence on Mr. Trump is unmistakable. Mr. Trump's wrecking  ball of a presidential bid - the gleeful smearing of his opponents, the  embracing of bluster as brand - has been a Roy Cohn number on a grand scale.  Mr. Trump's response to the Orlando massacre, with his ominous warnings of a  terrorist attack that could wipe out the country and his conspiratorial  suggestions of a Muslim fifth column in the United States, seemed to have been  ripped straight out of the Cohn playbook.
         
        "I hear Roy  in the things he says quite clearly," said Peter Fraser, who as Mr. Cohn's  lover for the last two years of his life spent a great deal of time with Mr.  Trump. "That bravado, and if you say it aggressively and loudly enough, it's  the truth - that's the way Roy used to operate to a degree, and Donald was  certainly his apprentice."
         
        For 13  years, the lawyer who had infamously whispered in McCarthy's ear whispered in  Mr. Trump's. In the process, Mr. Cohn helped deliver some of Mr. Trump's  signature construction deals, sued the National Football League for conspiring  against his client and countersued the federal government - for $100 million - for damaging the Trump name. One of Mr. Trump's executives recalled that he  kept an 8-by-10-inch photograph of Mr. Cohn in his office desk, pulling it out  to intimidate recalcitrant contractors.
         
        The two men  spoke as often as five times a day, toasted each other at birthday parties and  spent evenings together at Studio 54.
         
        And Mr.  Cohn turned repeatedly to Mr. Trump - one of a small clutch of people who knew  he was gay - in his hours of need. When a former companion was dying of AIDS,  he asked Mr. Trump to find him a place to stay. When he faced disbarment, he  summoned Mr. Trump to testify to his character.
         
        Mr. Trump  says the two became so close that Mr. Cohn, who had no immediate family,  sometimes refused to bill him, insisting he could not charge a friend.
         
        "Roy was an  era," Mr. Trump said in an interview, reflecting on his years with Mr. Cohn.  "They either loved him or couldn't stand him, which was fine."
         
        Mr. Trump  was asked if this reminded him of anyone. "Yeah," he answered. "It does, come  to think of it."
         
        The gossip  columnist Cindy Adams, who knew everyone, had no idea who he was.
  
         
        "This kid  is going to own New York someday," Mr. Cohn told her, gesturing at a tall  20-something bachelor at a dinner party in the early 1970s. "This is Donald  Trump."
         
        "Yeah, so?"  Ms. Adams recalled replying.
         
        Mr. Cohn,  the son of a prominent New York judge, had taken an uncommon interest in Mr.  Trump.
         
        The two had  met not long before at a private disco called Le Club, and instantly hit it off  while discussing a nettlesome obstacle for Mr. Trump. The Civil Rights Division  of the Justice Department was suing him and his father, accusing them of  refusing to rent to black tenants. Mr. Trump told Mr. Cohn that their lawyers  were urging them to settle.
        
     "Tell them to go to hell and fight the  thing in court,'" Mr. Trump later recalled Mr. Cohn advising him.
         
        Mr. Trump  did just that, with Mr. Cohn as his lawyer. Not only did Mr. Cohn countersue  the government for $100 million, he filed a blistering affidavit on Mr. Trump's  behalf, mocking the case. "The Civil Rights Division did not file a lawsuit,"  Mr. Cohn wrote. "It slapped together a piece of paper for use as a press release."  The Trumps ultimately settled the case by agreeing to make apartments available  to minority renters, while admitting no wrongdoing.
         
        For Mr.  Trump, the benefits of his new representation were obvious. Mr. Cohn was one of  the most famous and feared lawyers in America. He would later appear on the  cover of Esquire beneath an ironic halo, and earn a posthumous parody on "The  Simpsons."
         
        But Mr.  Cohn saw something in Mr. Trump, too.
         
        "He could  sniff out a power-to-be, Roy could," said Susan Bell, Mr. Cohn's longtime  secretary.
         
        After  helping convict the Rosenbergs as a young federal prosecutor and then working  in Washington as a top aide to McCarthy, Mr. Cohn had returned to New York, starting  a boutique practice in his shabby but elegant townhouse on East 68th Street.
         
        The  division of labor in the firm was clear.
         
        "We called  him the rainmaker," said Michael Rosen, a partner who handled many of the  firm's organized-crime cases. "We did all of the grunt work, if grunt work  means preparing the case and trying the case."
         
        Mr. Cohn  lived on the third floor, often traipsing downstairs in his bathrobe well after  the workday had begun and taking clients upstairs to a small sun porch. The  elevator rarely worked. In the winter, the lawyers stuffed towels around the  windows to keep out the cold.
         
        Parties and  business meetings tended to blur, with celebrities like Andy Warhol and Estée  Lauder crowding in and spilling out. "That townhouse was a workhorse," recalled  Mr. Trump, a familiar presence there himself.
         
        He and Mr.  Cohn became social companions, lunching at "21" or spending evenings at Yankee  Stadium in the owner's box of Mr. Steinbrenner, another Cohn client.
         
        After Mr.  Fraser entered Mr. Cohn's life, the two were frequent dinner guests at Donald  and Ivana's Trump Tower apartment, with its Michelangelo-style murals. They  were also regulars at Mr. Trump's box at the Meadowlands, the home of his  sports team, the New Jersey Generals of the short-lived United States Football  League.
         
        Mr. Cohn  was the master of ceremonies at a Trump birthday party at Studio 54; years  later, Mr. Trump returned the favor with a birthday toast of his own at a party  in the atrium of Trump Tower, joking that Mr. Cohn was more bark than bite.
         
        "We just  tell the opposition Roy Cohn is representing me, and they get scared," Mr.  Trump said, according to a cousin of Mr. Cohn's, David L. Marcus, who attended.  "He never actually does anything."
         
        Among the  many things Mr. Trump learned from Mr. Cohn during these years was the  importance of keeping one's name in the newspapers. Long before Mr. Trump posed  as his own spokesman, passing self-serving tidbits to gossip columnists, Mr.  Cohn was known to call in stories about himself to reporters.
         
        It was also  through Mr. Cohn that Mr. Trump met the political operative who has played a  leading, if behind-the-scenes, role in his campaign: Roger Stone.
         
        When Mr.  Stone, the roguish former Nixon adviser and master of the political dark arts,  came to New York in 1979 to court support for Ronald Reagan's presidential bid,  he arrived with a box of index cards filled with the names of actors and  producers. And Roy Cohn.
         
        "I made an  appointment and I pitched him on Reagan, and he said, 'You have to meet Donald  and Fred Trump,'" Mr. Stone recalled in an interview.
         
        Eventually,  Mr. Cohn and Mr. Trump became so inseparable that those who could not track  down Mr. Cohn knew whom to call.
         
        Once, Mr.  Cohn chartered a plane with friends, without Mr. Trump, trashing it during a  midair party. He refused to pay. So the airline found Mr. Trump, asking if he  could help.
  
  
        Mr. Trump  once said Mr. Cohn was a "vicious" protector. He called  Mr. Cohn, more amused than concerned.
         
        "I said,  'Roy, what are you going to do about this? I mean, you destroyed the plane,'"  Mr. Trump recalled. "He said, 'Eh, we'll pay them someday.'"
         
        By the time  Mr. Trump started getting serious with a Czech model named Ivana Winklmayr, Mr.  Cohn had become something of an expert on marriage.

         "It's difficult to imagine and admit that the  flush of the moment may become the flush of the toilet as the relationship goes  down the tubes," he wrote about the importance of prenuptial agreements in his  book "How to Stand Up for Your Rights - and Win!"
         
        According  to "Trump: The Greatest Show on Earth," a book by the journalist Wayne Barrett,  Mr. Cohn advised Mr. Trump against marrying Ms. Winklmayr, but insisted that if  he must, there had to be a prenuptial agreement. He would handle it himself.
         
        The  agreement, completed only weeks before the wedding, did not quantify Mr.  Trump's net worth - "impossible to accurately determine due to the illiquid  nature of his holdings" - and took a bearish view of Mr. Trump's earning  potential and a modest view of his tastes.
         
        "Donald's  standard of living is basically simple," it said, calling Mr. Trump's preferred  lifestyle "neither opulent nor extravagant."
         
        When the  marriage dissolved a few years after Mr. Cohn's death, Mrs. Trump's lawyers  charged that she had not had proper representation on the prenup. Her initial  lawyer had worked for Mr. Cohn on at least one case, and was a frequent  passenger on Mr. Cohn's yacht, the Defiance. The divorce case eventually ended  with a settlement.
         
        The prenup  was just one of many Trump deals, some more conventional than others, in which  Mr. Cohn was intimately involved.
         
        He used his  connections to help Mr. Trump secure zoning variances and tax abatements  critical to the construction of the Grand Hyatt Hotel and the Trump Plaza.
         
        After one  Cohn coup, Mr. Trump rewarded him with a pair of diamond-encrusted cuff links  and buttons in a Bulgari box.
         
        And if Mr.  Cohn did not always feel comfortable charging a friend for his services, Mr.  Trump was hardly one to put up a fight.
         
        "Roy said,  'I'll leave it to Donald to give me what he thinks is fair,'" Mr. Fraser  recalled of one lengthy Trump tax case in particular. "But, of course, Donald  didn't give him anything."
         
        Some work  would have been difficult to bill. For instance, Mr. Cohn lobbied his friends  in the Reagan White House to nominate Mr. Trump's sister Maryanne Trump Barry  to the federal bench. (Questioned last year about this, Mr. Trump said his  sister "got the appointment totally on her own merit.")
         
        "He was a  very good lawyer if he wanted to be," Mr. Trump said in the interview.
         
        Asked about  Mr. Cohn in 1980, Mr. Trump was more blunt in his assessment: "He's been  vicious to others in his protection of me."
         
        Defiant to  the End
  
  
        It started  with a cut that would not stop bleeding.
         
        Mr. Cohn's  diagnosis came not long after his former companion, Russell Eldridge, had  gotten his. Mr. Eldridge had spent most of his final days in a private suite  overlooking Central Park in Mr. Trump's Barbizon Plaza Hotel.
         
        Ms. Bell,  Mr. Cohn's secretary, recalled that Mr. Trump's secretary, Norma Foerderer, had  billed Mr. Cohn for the room, and later called to say that Mr. Cohn had not  paid.
         
        "I said, 'Guess  what, Norma, he's not going to,'" Ms. Bell said. "And she kind of knew it."
         
        Mr. Cohn  remained in his townhouse. Until the end - and even under interrogation by Mike  Wallace on "60 Minutes" - he insisted that he had liver cancer, not AIDS.

        He received  experimental AZT treatments in Washington and continued working. But his  clients could not help but notice that his health was deteriorating.
         
        Mr. Trump  started gradually moving cases elsewhere, he said, never telling Mr. Cohn why.  "There's no reason to hurt somebody's feelings," he said.
         
        "He was so  weak," Mr. Trump added. "He was so weakened that he really couldn't do it."
         
        Mr. Cohn  never spoke about Mr. Trump's decision, but was plainly crushed, according to  Ms. Bell. She remembers it happening not gradually, but "overnight."
         
        Even as his  health was failing, Mr. Cohn, whom government prosecutors had unsuccessfully  pursued for decades on charges including conspiracy, bribery and fraud, faced a  final indignity: He was facing the prospect of disbarment. Among other  offenses, he was charged with coercing a dying multimillionaire client - during  a late-night visit to the man's hospital room - to amend his will to make Mr.  Cohn an executor of his estate.
         
        The  hearings were closed to the public. But true to form, Mr. Cohn, riding to the  daily proceedings in a red Cadillac convertible, insisted on a spectacle,  describing his accusers as "a bunch of yo-yos just out to smear me up."
         
        The  prominent figures whom Mr. Cohn summoned to testify on his behalf included  Barbara Walters and William F. Buckley Jr.
         
        And, of  course, Mr. Trump. He described his friend in simple terms.
         
        "If I summed  it up in one word," Mr. Trump told the hearing panel, "I think the primary word  I'd use is his loyalty."
         
        Gaunt,  frail and besieged, Mr. Cohn nevertheless managed to attend a dinner with Mr.  Fraser at Mar-a-Lago in Palm Beach, Fla., shortly after Mr. Trump purchased the  property in late 1985. It was a last glimpse at his final, fair-haired project.
         
        "I made  Trump successful," he would occasionally boast, according to Mr. Marcus, Mr.  Cohn's cousin, a former journalist who chronicled Mr. Cohn's last months for  Vanity Fair.
         
        In June  1986, Mr. Cohn was disbarred for "unethical," "unprofessional" and  "particularly reprehensible" conduct.
         
        To this  day, Mr. Trump rues the outcome. "They only got him because he was so sick,"  Mr. Trump said in the interview. "They wouldn't have gotten him otherwise."
         
        During his  final days, Mr. Cohn called Mr. Trump, ostensibly for no particular reason. "It  was just a call: 'How are things going?'" Mr. Trump recalled. "Roy was the kind  of guy - I don't think he ever thought he was dying, frankly."
         
        About a  week later, in August 1986, Mr. Trump received another call.
         
        Mr. Trump  hung up the phone, repeating the news to an associate in his office: Roy Cohn  was dead.
         
        "I said,  'Wow, that's the end of a generation,'" Mr. Trump remembered. "'That's the end  of an era.'"
         
        Mr. Fraser  inherited all of Mr. Cohn's possessions: the townhouse, his weekend place in  Greenwich, Conn., his Rolls-Royce, his private plane and much more. But the  Internal Revenue Service, collecting on Mr. Cohn's tax debts, confiscated  nearly everything.
         
        He did get  to keep the cuff links Mr. Trump had given Mr. Cohn. Years later, Mr. Fraser  had them appraised; they were knockoffs, he said.
         
        Mr. Fraser  soon returned to his native New Zealand, where he now works as a  conservationist at the Auckland Zoo. He has not spoken with Mr. Trump since Mr.  Cohn's death, but he has no doubt that if his former lover were still alive, he  would be an enthusiastic supporter of the Trump campaign.
