“We're finally learning the truth about this president. And yes, there has to be consequences. Yes, there has to be accountability. Yes, I think there's enough evidence now for the House of Representatives to move forward with impeachment,” O'Rourke said in an interview with The Dallas Morning News published on Saturday.

“This is our country, and this is the one chance that we get to ensure that it remains a democracy and that no man, regardless of his position, is above the law.”

O'Rourke openly supported impeachment while running unsuccessfully for a Texas Senate seat. But he also voted twice against moving toward impeachment proceedings, The Dallas Morning News noted.

O'Rourke said in March that the 2020 election may be the best way to remove Trump from office.

"I think the American people are going to have a chance to decide this at the ballot box in November 2020, and perhaps that's the best way for us to resolve these outstanding questions," he said at the time.

But O'Rourke told The Dallas Morning News that Trump should face impeachment, saying he has put the nation's democracy at risk. He added that Trump “welcomed the participation of a foreign power into our election, that sought to sway that election in his favor” and “clearly obstructed justice in firing the principal investigator," a reference to former FBI Director James Comey James Brien ComeyDemocrats fear Russia interference could spoil bid to retake Senate Book: FBI sex crimes investigator helped trigger October 2016 public probe of Clinton emails Trump jabs at FBI director over testimony on Russia, antifa MORE.

“[Though] lying and dissembling and creating such a climate of fear within the White House and government ... he almost got away with it,” O'Rourke said.
