On CBS's "Face the Nation," host Margaret Brennan asked Cheney if she would call for Gaetz's resignation.

"You know, as the mother of daughters, the charges certainly are sickening. And as the Speaker [Nancy PelosiNancy PelosiNew Alzheimer's drug sparks backlash over FDA, pricing Sunday shows preview: Biden foreign policy in focus as Dem tensions boil up back home It's not just Manchin: No electoral mandate stalls Democrats' leftist agenda MORE (D-Calif.)] noted, there's an ethics investigation underway. There are also criminal investigations underway, and I'm not gonna comment further on that publicly right now," Cheney said.

Cheney also refused to say if she was surprised by the allegations. 

The Department of Justice has opened a probe into allegations that Gaetz had sex with a minor and violated sex trafficking laws. It was reported last week that Gaetz had sent $900 through the Venmo app to accused sex trafficker Joel Greenberg, who in turn sent the same amount of money to three young women, categorizing the payments for "Tuition" or "School."

It was announced last week that the House Ethics Committee had opened an investigation into Gaetz regarding allegations of illegal drug use and sharing with colleagues on the House floor nude photos of young women.

Gaetz has denied having an inappropriate relationship with a 17-year-old amid reports of the Justice Department investigation.

He told a crowd in Florida on Friday that he would not be intimidated by allegations against him, vowing the "truth will prevail."

"I have not yet begun to fight," he said at a speech at the Save America Summit.

Prior to Cheney's interview, Pelosi said that it was “up to the Republicans to take responsibility for that” when asked if Gaetz should resign from Congress.
