Rep. Elizabeth Cheney lambasted former President Donald Trump and his supporters in the Republican party during a speech Tuesday.

Cheney called Trump a “domestic threat” and accused him of working against the Constitution and the rule of law. She was speaking in New Hampshire at St. Anselm College.

“At this moment when it matters most, we are also confronting a domestic threat that we’ve never faced before: a former president who’s attempting to unravel the foundations of our constitutional Republic, aided by political leaders who have made themselves willing hostages to this dangerous and irrational man,” said Cheney.

Cheney was among ten Republicans who voted to impeach Trump during the second impeachment on charges that he incited an insurrection on Jan. 6 when some of his supporters rioted at the U.S. Capitol. She criticized him for continuing to reject the official results of the presidential election.
