Walter Isaacson and Evan Thomas titled their classic group portrait of Harry S. Truman’s foreign policy team, “The Wise Men.” A book about Donald Trump’s associations might be called “The Wise Guys.”

Mario Puzo would’ve been just the man to write it. Martin Scorsese could option the movie rights.

And if he’s not in prison when filming starts, former Trump campaign chairman Paul Manafort deserves a role. Though Manafort hasn’t been accused of Mafia membership, Smooth Paulie certainly acts the part, judging from testimony at his trial in federal court on charges of fraud and tax evasion. He has a closet full of suits worthy of John Gotti (though even the Dapper Don might have balked at an ostrich-skin windbreaker) and a maze of offshore bank accounts dense enough to addle Meyer Lansky.

When Manafort’s turncoat lieutenant Rick Gates took the stand to detail their alleged conspiracies, I was transported to the day back in 1992 when Gotti’s underboss Sammy Gravano began singing at the federal courthouse in Brooklyn. Gotti’s lawyers attacked Sammy the Bull by demanding to know how many people he’d whacked. Manafort’s team asked Gates how many affairs he’s had.
