Conservative New York Times columnist Bret Stephens said Tuesday that President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE should resign or be impeached.

Stephens made the comment in a tweet after longtime Trump lawyer Michael Cohen pleaded guilty to eight federal charges, possibly implicating Trump in the process.

“I’ve been skeptical about the wisdom and merit of impeachment,” Stephens tweeted. “Cohen's guilty plea changes that. The president is clearly guilty of high crimes and misdemeanors. He should resign his office or be impeached and removed from office.”

He also pleaded guilty to a campaign finance violation —

making an excessive campaign contribution on Oct. 27, 2016. The date given is when Cohen finalized a $130,000 payment to adult-film star Stormy Daniels as part of a nondisclosure agreement about an alleged affair she had with Trump.

Cohen testified that he made the payment at the direction of “a candidate for federal office,” referencing Trump.

Cohen’s lawyer, Lanny Davis, said Cohen’s guilty plea and testimony indicate that Trump is also guilty of a crime.

"Today he stood up and testified under oath that Donald Trump directed him to commit a crime by making payments to two women for the principal purpose of influencing an election," Davis, who is also an opinion contributor for The Hill, tweeted. "If those payments were a crime for Michael Cohen, then why wouldn't they be a crime for Donald Trump?"

Cohen also testified that he made an illegal campaign contribution of $150,000, the same amount allegedly paid to former Playboy model Karen McDougal for the rights to her story about an alleged affair with Trump.
