Dick Cheney urged Wyoming voters to re-elect his daughter, Rep. Liz Cheney, in her upcoming primary in a new campaign ad.

Dick Cheney, who served as President George W. Bush's vice president, said in the ad that Donald Trump was the greatest threat to the country.

Dick Cheney called Trump a "coward" after he tried to steal the last election.

Voters in Wyoming will decide on August 16 whether to keep Liz Cheney in office. Her main opponent is a local natural resources attorney who was endorsed by Trump. Hageman had a 22-point lead over Liz Cheney in a survey conducted in July.

It's one of the most closely watched races this year as Trump tries to oust Liz Cheney from Congress over her criticism of his efforts to overturn the 2020 election and his role in the January 6, 2021, Capitol attack. Liz Cheney is a member of the committee.

He lost his election and lost a lot. "I know it, he knows it, and I think most Republicans know it," Liz Cheney's father said in the video.

He said thatLiz never backs down from a fight. She will lead the effort to make sure Donald Trump doesn't return to the White House. She will be successful.

Liz Cheney has represented Wyoming's sole congressional district since 2015, a seat her father once held.

Bush and Cheney have been criticized by Trump for their foreign policy decisions. Dick Cheney and his daughter were called warmongers by Trump.

"The Cheneys are warmongers who have been plunging us into new conflicts for decades, spilling American blood and spending American treasure all over the world," Trump said during a Hageman campaign rally.
