Former U.S. Rep. Liz Cheney implored new college graduates to not compromise when it comes to the truth, excoriating her House Republican colleagues for not doing enough to combat former President Donald Trump’s lies that the 2020 election was stolen.

In a commencement speech at Colorado College, the Wyoming Republican repeated her fierce criticisms of Trump but steered clear of talking about his 2024 reelection campaign or her own political future.

Cheney, who graduated from Colorado College in 1988, recalled being a political science student walking into a campus building where a Bible verse was inscribed above the entrance that read, “You shall know the truth and the truth shall make you free.”

“I had to choose between lying and losing my position in House leadership,” Cheney said Sunday in Colorado Springs, connecting her experiences as a student to her work in the U.S. House of Representatives. “As I spoke to my colleagues on my last morning as chair of the Republican Conference in May of 2021, I told them that if they wanted a leader who would lie, they should choose someone else.”

In three terms in office, Cheney rose to the No. 3 GOP leadership position in the House, a job she lost after voting to impeach Trump for the Jan. 6, 2021, insurrection at the Capitol and then not relenting in her criticism of the former president.

Cheney’s speech touched on themes similar to those she has promoted since leaving office in January: addressing her work on the House committee investigating the Jan. 6 2021 attack on the U.S. Capitol and standing up to the threat she believes Trump poses to democracy. She also encouraged more women to run for office and blasted one of the election-denying attorneys who worked for Trump after the 2020 election for recent remarks about college students voting.

“Cleta Mitchell, an election denier and adviser to former President Trump, told a gathering of Republicans recently that it is crucially important to make sure that college students don’t vote,” Cheney said. “Those who are trying to unravel the foundations of our republic, who are threatening the rule of law and the sanctity of our elections, know they can’t succeed if you vote.”

In an audio recording of Mitchell’s presentation from a recent Republican National Committee retreat, she warns of polling places on college campuses and the ease of voting as potential problems, the Washington Post reported.

Most students and parents in the audience applauded throughout Cheney’s remarks, yet some booed. Some students opposing the choice of Cheney as speaker turned their chairs away from the stage as she spoke.

Cheney’s busy speaking schedule and subject matter have fueled speculation about whether she may enter the 2024 GOP presidential primary since she left office. Candidates ranging from Florida Gov. Ron DeSantis to former South Carolina Gov. Nikki Haley have calibrated their remarks about Trump, aiming to counter his attacks without alienating the supporters that won him the White House seven years ago.

Though some have offered measured criticisms, no declared or potential challenger has embraced anti-Trump messaging to the same extent as Cheney. She did not reference her plans on Sunday but has previously said she remains undecided about whether she wants to run for president.

Though she would face an uphill battle, Cheney’s fierce anti-Trump stance and her role as vice chairwoman of the House committee elevated her platform high enough to call on a national network of donors and Trump critics to support a White House run.

A super PAC organized to support of her candidacy has remained active, including purchasing attack ads on New Hampshire airwaves against Trump this month.

After leaving office and being replaced by a Trump-backed Republican who defeated her in last year’s primary, Cheney was appointed to a professorship at the University of Virginia and wrote “Oath and Honor,” a memoir scheduled to hit shelves in November.

Two of Cheney’s five children as well as her mother are also graduates of the liberal arts college.

Cheney’s speaking tour appears to be picking up. She is scheduled to appear Thursday at the Mackinac Policy Conference in Michigan.
