Jeffrey Toobin: “Since joining Trump’s team, Giuliani has greeted every new development as a vindication, even when he’s had to bend and warp the evidence in front of him. Like Trump, he characterizes the Mueller probe as a ‘witch hunt’ and the prosecutors as ‘thugs.’ He has, in effect, become the legal auxiliary to Trump’s Twitter feed, peddling the same chaotic mixture of non sequiturs, exaggerations, half-truths, and falsehoods. Giuliani, like the President, is not seeking converts but comforting the converted.”
“This has come at considerable cost to his reputation. As a prosecutor, Giuliani was the sheriff of Wall Street and the bane of organized crime. As mayor, he was the law-and-order leader who kicked ‘squeegee men’ off the streets of New York. Now he’s a talking head spouting nonsense on cable news. But this version of Giuliani isn’t new; Trump has merely tapped into tendencies that have been evident all along.”
“Trump learned about law and politics from his mentor Roy Cohn, the notorious sidekick to Joseph McCarthy who, as a lawyer in New York, became a legendary brawler and used the media to bash adversaries. In the early months of his Presidency, as Mueller’s investigation was getting under way, Trump is said to have raged, ‘Where’s my Roy Cohn?’ In Giuliani, the President has found him.”
