WATCH: Newt pushes conspiracy theory Biden White House wants to 'exterminate' Republicans

Only weeks after Republican lies about election fraud incited a fatal insurrection at the U.S. Capitol, former Speaker Newt Gingrich pushed a new conspiracy theory.

On the first full day of the Biden administration, Gingrich blasted the new administration because of public discussions over the 14th Amendment banning people who commit sedition after taking an oath to defend the Constitution. Many legal experts have said that applies to Sen. Ted Cruz (R-TX) and Sen. Josh Hawley (R-MO).

"Well look, I think you are seeing the hysteria of the Biden system. Because it's not really about Biden himself. It's this entire team around him who are radicals who believe if they could exterminate the Republicans that would be one way to get to unity. As a New York Times columnist wrote this morning, you know, if Biden really wanted unity, he would start by lynching Vice President Pence. That just gives you a sense of the ferocity and the anger and the hatred that underlies the modern left. And I think that Cruz showed enormous courage," Gingrich argued. "He always has."
