GOP Rep. Adam Kinzinger: 'My party has utterly failed the American people at truth'

• GOP Rep Adam Kinzinger, one of two Republicans on the Jan. 6 committee, slammed his party Sunday.
• Kinzinger has charged that Trump knew he lost the 2020 presidential election ahead of the Capitol riot.

GOP Rep. Adam Kinzinger, one of two Republicans in the Jan. 6 committee, said on Sunday that former President Donald Trump "knew what he was doing" ahead of the Capitol insurrection and his party has failed "at truth."

In an interview with ABC's "This Week," when asked if he thinks Trump should be prosecuted, Kinzinger told host George Stephanopoulos, "I certainly think the president is guilty of knowing what he did, seditious conspiracy, being involved in these, you know, kind of different segments of pressuring the DOJ, vice president, et cetera."

"Unfortunately, my party has utterly failed the American people at truth. It makes me sad, but it's a fact," Kinzinger, one of two Republicans on the Jan 6. committee, said.

Kinzinger has charged that Trump knew he lost the 2020 presidential election ahead of the Capitol riot.

"The president absolutely tried to overthrow the will of the people and he tried to do it initially through misinformation, through the Department of Justice, through pressuring the Vice President, and then on January 6," he said last week on CBS's "Face the Nation."

According to a new Ipsos/ABC News poll, a majority of Americans Trump say should be criminally charged for his role in the Jan. 6 Capitol riot.

"Obviously, you know, we're not a criminal charges committee. So I want to be careful and specifically using that language," Kinzinger said Sunday. "But I think what we're presenting before the American people certainly would rise to a level of criminal involvement by a president and definitely failure of the oath has to matter here, your personal demand to stand for the Constitution has to matter."
