Donald Trump trusted Michael Cohen for years. Now his lawyer doubts Cohen’s credibility.

On July 8, ABC News’s George Stephanopoulos asked President Trump’s lawyer Rudolph W. Giuliani whether he was concerned that Trump’s longtime lawyer, Michael Cohen, might flip on the president.

“I have no concerns that Michael Cohen is going to do anything but tell the truth, and if he does, as I said, there’s no suggestion that anything happened,” Giuliani said at the time.

Now with Cohen reportedly prepared to flip on Trump less than two weeks later, Giuliani is singing a much different tune about a man he once called an “honest, honorable lawyer.”

This guy is a proven liar,” Giuliani told CNN on Thursday. “A year ago, when I wasn’t his lawyer, people in your profession told me this guy will flip because he is an inherent, pathological liar.”

.. the investigations into Cohen and Russian election interference could come down, in part, to Cohen’s credibility. Or at least Trump’s legal team seems to think so.
