After he was sentenced to three years in prison on Wednesday for tax fraud, lying to Congress, and campaign-finance violations he said he committed at the president’s direction, Michael Cohen is going full John Dean. In an interview with ABC News’s George Stephanopoulos that aired Friday, the lawyer and fixer who was once so loyal to Donald Trump that he claimed he’d “take a bullet” for him, said that not only did Trump instruct him to pay off Stormy Daniels and Karen McDougal, but he knew that doing so was “wrong.”

“Of course [he knew it was wrong],” Cohen said. “He was very concerned about how this would affect the election.” He explained to Stephanopoulos that “nothing at the Trump Organization was ever done unless it was run through Mr. Trump. He directed me to make the payments, he directed me to become involved in these matters.”

“He knows the truth. I know the truth. Others know the truth,” Cohen continued. “And here is the truth: people of the United States of America, people of the world, don’t believe what he is saying. The man doesn’t tell the truth. And it is sad that I should take responsibility for his dirty deeds.”

“I am done with the lying,” Cohen said. “I am done being loyal to President Trump.”

Cohen’s assertions underscored the legal liability the former fixer may pose to the president through his cooperation with special counsel Robert Mueller, which began after he pleaded guilty to tax fraud and campaign-finance violations in August. In November, Cohen fessed up to lying to Congress about the nature and timing of Trump’s business dealings with Russia.

Both matters have raised the specter of Trump’s impeachment and possibly even indictment, which seems to have rattled the president, who has now spent months lashing out at his “weak” former attorney. In one of his latest broadsides, Trump charged that Cohen was lying to “embarrass the president” and get a reduced prison sentence. But Cohen told Stephanopoulos that he had no desire to humiliate Trump, and that Mueller has a “substantial amount of information” to corroborate his assertions about the hush agreements and the Russia dealings.

In the face of such evidence, Trump’s legal team has gradually shifted its defense. After initially saying he had “NOTHING TO DO WITH RUSSIA,” the president this week claimed his dealings with the Kremlin constituted “peanut stuff” that was actually “very legal & very cool.” And after long denying that the president had any knowledge of the hush payments, this week Trump lawyer Rudy Giuliani told the Daily Beast that “Nobody got killed, nobody got robbed . . . This was not a big crime.”
