Dick Cheney called Donald Trump a "coward" and a "threat to our republic" in a new ad for his daughter's congressional campaign.

"In our nation's 246-year history, there has never been an individual who is a greater threat to our republic than Donald Trump," Cheney said in the ad. After the voters rejected him, he tried to steal the election using lies and violence. He doesn't know what he's doing. A man wouldn't lie to his friends.

In Wyoming, Liz Cheney is in a close race for the Republican nomination in the general election. Cheney, who is running for a fourth term in office, is the vice chairwoman of the select committee investigating Trump's role in the riot at the U.S. Capitol.

According to testimony from several former members of the Trump administration as well as Republican election officials and lawmakers in states Trump lost in 2020, the committee has made a case that he knowingly pushed false claims that election fraud cost him victory In the ad for his daughter, Dick Cheney said the same thing.

He lost his election and he lost a lot of money. The former vice president believes most Republicans know it. Liz Cheney's mother and I are proud of her for standing up for what's right and honoring her oath to the Constitution.

"There is nothing more important she will ever do than lead the effort to make sure Donald Trump is never again near the Oval Office, and she will succeed," Cheney said.

The 10 House Republicans who voted to impeach Trump were led by Liz Cheney. She was stripped of her leadership role in the party after the Republican Party censured her for that vote.

The new ad on Truth Social has yet to be responded to by Trump.
