Scoop: Viral Cheney ad to air on Fox News

A viral ad in which former Vice President Dick Cheney attacks former President Trump as a "coward" will begin airing on Fox News on Tuesday, a week before his daughter Rep. Liz Cheney (R-Wyo.) faces a Trump-backed primary challenge, Axios has learned.

Driving the news: The ad, which initially aired solely in Wyoming, got so much attention that Cheney's campaign has decided to take it directly to Trump's favorite programs. The ad will air twice daily this week during "Fox & Friends" and once daily on Sean Hannity's prime-time show.

Why it matters: Polls show Liz Cheney — a fierce GOP Trump critic and the vice chair of the House Jan. 6 committee — is in danger of being ousted by her Trump-backed opponent, Harriet Hageman.

• But Cheney is playing the long game, potentially in preparation for a 2024 presidential run.
