Cheney's new campaign ad focuses on opponents' claims about the 2020 election

In the closing weeks of her campaign, Rep. Liz Cheney, a Republican, is up with a new TV ad that contrasts her primary opponents' stances about fraud in the 2020 election with her own.

The ad, first shared with CBS News, features comments made about the 2020 election by three of her primary opponents during their June debate.

It opens up with her main opponent, Trump-backed trial attorney Harriet Hageman saying, "We have serious questions about the 2020 election."
