Rep. Liz Cheney (R-Wyo.) on Wednesday said her father, former Vice President Dick Cheney (R), is “deeply troubled” about the state of the Republican Party.

“My dad is deeply troubled about where our party is, deeply troubled about where the country is,” Cheney said during an event hosted by the Aspen Institute.

She said her father, who served under former President George W. Bush, has been a “tremendous source of advice and guidance and wisdom for me.”

Liz Cheney has been among the most vocal GOP critics of former President Trump’s failed campaign to overturn the results of the 2020 presidential election and the Republican Party’s support of his efforts.
