Sen. Elizabeth Warren (D-Mass.) on Friday called on the House to begin impeachment against President Trump in light of the findings in the special counsel’s report.

The high-profile senator, who is vying to take on Trump in 2020, said Robert S. Mueller III laid out the facts so that Congress would act.

“The severity of this misconduct demands that elected officials in both parties set aside political considerations and do their constitutional duty,” Warren said. “That means the House should initiate impeachment proceedings against the President of the United States.”

Trump has been celebrating the report as an exoneration, but others see a president who several times tried to obstruct justice and was thwarted by staffers. While Mueller determined there was insufficient evidence to charge Trump with criminal conspiracy, he made no assessment on the obstruction question except to note that “Congress has the authority to prohibit a President’s corrupt use of his authority in order to protect the integrity of the administration of justice.”

“To ignore a President’s repeated efforts to obstruct an investigation into his own disloyal behavior would inflict great and lasting damage on this country,” Warren said on Twitter, “and it would suggest that both the current and future Presidents would be free to abuse their power in similar ways.”

House Democratic leaders have been unenthusiastic about launching an impeachment process that would divert attention from the policies they want to highlight ahead of the 2020 election. Speaker Nancy Pelosi and House Majority Leader Steny H. Hoyer have batted down demands by some in their party to impeach Trump. Many Democrats have advocated letting voters decide.

Warren’s move could win favor with liberal voters, whose caucus in Congress is more strident about impeachment.

Impeachment is not a priority for most Democratic voters, polls have shown, although that could change now that the Mueller report has been released.
