On CBS's "Face the Nation," host Margaret Brennan asked Krebs whether he believes Trump is attempting to undermined future elections, noting that the former president said during a recent rally that he is seeking to completely overhaul the U.S. election system.

"Without question. It's happening at four different levels, both state legislatures and state elected officials, some of the folks running for secretary of state in Arizona and Georgia, but we're also seeing [it] in the U.S. Congress," said Krebs.

Brennan noted that was an extraordinary remark for Krebs, a lifelong Republican, to make and asked how these claims continue to occur.

"They're afraid to speak up because they're afraid the former president is going to try to primary them, and then the other piece is that they've activated and lost control of their voting base, the people that are going to put them in power," Krebs said.

"It's gotten out of control, so, again, this is a death spiral. They've lost control, and they don't have the ability to rein it back in," Krebs added.
