Harvard law professor Alan Dershowitz said Wednesday that he expects special counsel Robert MuellerRobert (Bob) Swan MuellerGraham: Mueller investigation a 'political rectal exam' House progressive: Pelosi 'has it right' on impeachment Democrats talk subpoena for Mueller MORE's report on his investigation into Russian interference in the 2016 election will contain "lots of sins" related to President TrumpDonald John TrumpNASA exec leading moon mission quits weeks after appointment The Hill's Morning Report — After contentious week, Trump heads for Japan Frustration boils over with Senate's 'legislative graveyard' MORE, but no "impeachable offense."

"The president's not going be impeached unless massive new information comes out," Dershowitz said on "America's Newsroom" on Fox News.

"I suspect the special counsel’s report will contain lots and lots of sins based on political and based on circumstantial evidence, but I don’t think he’s going to come up with an impeachable offense," Dershowitz added.

The attorney, who appears regularly on Fox News and often defends the president, argued that the most incriminating evidence against Trump thus far is a "very, very questionable campaign contribution issue."

"So I don't think we’re in impeachment land," he added.

Dershowitz also pushed back on Trump's assertion a day earlier that he's not worried about being impeached because "the people would revolt." Dershowitz said Americans would have to accept the result if Trump is removed lawfully.

Dershowitz's comments came on the same day that a judge sentenced Trump's former attorney, Michael Cohen, to three years in prison. The sentence stems from eight federal charges he pleaded guilty to in August, including campaign finance violations for paying off women alleging affairs with Trump in order to prevent damaging information from surfacing during the 2016 presidential campaign.

Other charges included bank and tax fraud, and lying to Congress about plans to build a Trump property in Moscow.

The Mueller investigation has thus far implicated five former Trump associates and more than 20 Russian nationals.

The president has repeatedly railed against the probe as a "witch hunt," and has insisted that he did not collude with Russia in the election. He has also downplayed the hush money payments, claiming they were a "simple private transaction" and that he should not be held accountable if Cohen did not properly record them as a contribution.
