Former Wyoming GOP Rep. Liz Cheney was reportedly greeted with boos and turned chairs from some of the graduates at Colorado College on Sunday where she delivered a commencement address.

Cheney, an outspoken critic of former President Donald Trump who lost her bid for re-election, discussed her opposition to Trump during the address.

Cheney, who was a member of the House Select Committee on Jan. 6, also repeatedly criticized her GOP colleagues for not publicly denouncing Trump’s claims of widespread fraud during the 2020 election, according to the Daily Mail.
