Trump, who once bleated “Where’s my Roy Cohn?” in his anger about Jeff Sessions recusing himself, wanted a lawyer who was whip-smart, amoral, ruthless and predatory. Cohen was merely Renfield to Trump’s Dracula, gratefully eating insects and doing the fiend’s bidding.

Trump used Cohen for dirty deeds done dirt cheap, as ACDC sang.

The Wall Street Journal reported that Trump showed up late to Cohen’s son’s bar mitzvah and then made a belittling speech about how he had come only because Cohen had begged him and everyone around him. The Times revealed last April that Trump had regularly threatened to fire Cohen and quoted Roger Stone saying that Trump mocked Cohen for overpaying for Trump real estate.

With a few exceptions in his inner circle and with family, Trump doesn’t give loyalty or deserve it. That’s why Republicans on the Hill who so obsequiously stand by him will eventually learn it wasn’t worth it, just as Cohen warned them.

Loyalty is a rare commodity in Washington. And Cohen is not the most wretched sycophant in political history. That honor goes to Andrew Young, a slavishly devoted aide to John Edwards during the 2008 campaign who served as a driver, personal shopper, handyman and butler to the North Carolina senator.

When Edwards had an affair with campaign videographer Rielle Hunter and a pregnancy ensued, he persuaded Young to say that he was the father. Edwards also got Young to go on the lam with his wife, who was a nurse, and Hunter and the baby, hiding out in fancy hotels and a posh home near Santa Barbara — an odyssey financed by Young and Bunny Mellon. As Young wrote in “The Politician,” inside the campaign there was “a cult-like atmosphere” that encouraged extreme sycophancy.

When Trump gave me a tour of his campaign headquarters in Trump Tower in the summer of 2016, he introduced Cohen as “my lawyer.” Cohen looked furtive, standing around with Trump favorites Corey Lewandowski and Hope Hicks and a few young guys at a desk and a whole bunch of Trump portraits and cutouts and a wall with pictures of Trump’s vanquished primary rivals.

It was the least presidential campaign headquarters ever, with the drywall still unfinished in some places. As The Times reported, Cohen, who had been pushing for years for Trump to be president, was jealous of the attention Trump gave Lewandowski.
