President Trump argued that Democrats can’t impeach him because special counsel Robert Mueller did not find that he committed any crimes.

“Only high crimes and misdemeanors can lead to impeachment. There were no crimes by me (No Collusion, No Obstruction), so you can’t impeach,” Trump wrote on Twitter Monday. “It was the Democrats that committed the crimes, not your Republican President! Tables are finally turning on the Witch Hunt!”

In the 448-page redacted report released publicly last Thursday, Mueller’s team found there was no evidence that Trump or his campaign associates conspired with the Russians during the 2016 election.

But the report, released by Attorney General William Barr, struggled with the idea of whether Trump obstructed justice, declaring that if they had confidence after “a thorough investigation of the facts that the President clearly did not commit obstruction of justice, we would so state.”

Mueller included 10 instances in which Trump tried to interfere in the investigation, including by trying to pressure White House counsel Don McGahn to fire the special counsel.

Rep. Jerrold Nadler, chairman of the House Judiciary Committee, where impeachment proceedings would begin, said Sunday that Democrats shouldn’t reach a conclusion until they see the unredacted version of the report and get to question Mueller and Barr.

“Some of this would be impeachable,” the New York Democrat said on NBC’s “Meet the Press.” “Obstruction of justice, if proven, would be impeachable.”

Sen. Elizabeth Warren, a Democratic presidential candidate, said the report made clear the Russians meddled in the election to aid Trump and the campaign welcomed the help. After entering the White House, Trump acted to derail Mueller’s investigation, she claimed, grounds enough to begin impeachment hearings.

“Mueller put the next step in the hands of Congress: ‘Congress has authority to prohibit a President’s corrupt use of his authority in order to protect the integrity of the administration of justice,'” she wrote on Twitter last week. “The correct process for exercising that authority is impeachment.”

The Constitution provides Congress with the ability to remove a president through impeachment — a political rather than a criminal process.

It allows impeachment in cases of “treason, bribery, and other high crimes and misdemeanors,” which covers allegations of misconduct, dereliction of duty, abuse of authority and unbecoming conduct.

Trump and his Republican allies have claimed that Mueller’s investigation was launched by Democrats upset by his White House victory and was based on unsubstantiated information in a dossier compiled by former British spy Christopher Steele.

They have also called on Barr to investigate the beginnings of the Mueller probe.
