Harvard law professor Alan Dershowitz said late Wednesday that it “would not be an impeachable offense” for President Trump to fire special counsel Robert Mueller because “it wouldn’t be a crime.”

Fox News host Tucker Carlson asked Dershowitz if there was “any oversight of any kind of the special counsel” like there is with anyone else “who wields power in society.”

{mosads}”We can defeat our elected representatives in elections, we can recall or impeach a president or judges. The special counsel, we are told, can’t be fired because that itself would be an impeachable offense. So, is there any oversight of any kind of the special counsel?” he asked.

“First of all, firing the special counsel would not be impeachable offense, because it wouldn’t be a crime. The president would have authority to do it but it would be politically very damaging to do it,” Dershowitz replied.

Trump has insisted he had no plans to fire Mueller despite continued speculation by political pundits that he would do so since the special counsel’s investigation into Russia’s election meddling and possible collusion between the president’s campaign and Moscow was launched in May 2017.

The president has, however, stepped up his criticism of Mueller and his investigation on Twitter, including a tweet on Wednesday morning that included an image of Mueller, former FBI Director James Comey, former President Clinton and his wife Hillary Clinton and other critics behind bars for “treason.”

“Now that Russia collusion is a proven lie, when do the trials for treason begin?” the photo caption reads.

Dershowitz late Wednesday also argued that the special counsel’s final report is “simply an accusation” that contains testimony from prosecution witnesses and can be rebutted by the president’s legal team.

“The special counsel is just another prosecutor,” he said. “We must see the other side of the story before we can come to any conclusion.”
