Carlson has even defended Moscow’s buildup of troops along the border with Ukraine — and President Vladimir Putin’s rationale for it — in a stark departure from the tough-on-Russia posture that has defined the Republican Party since the start of the Cold War. Meanwhile, Ukraine remains under active threat from an invasion that some are warning could be just the first domino to fall in Eastern Europe.

“I don’t agree with those views,” Florida Sen. Marco Rubio, the top Republican on the Senate Intelligence Committee, said when asked about Carlson’s monologues. “[It’s] the U.S. interest not just in Europe but around the world in not having countries decide, ‘That belongs to us, we’re going to go ahead and take it.’”

Some GOP senators rolled their eyes when asked about Carlson’s attacks and indicated that the far-right Fox host isn’t impacting their calculus on an emerging legislative path, even as his views are picking up steam among the base.

“I get great intel briefings and we have trusted advisers that provide many points of view. And I would say I’m pretty well educated on this subject,” Ernst, a combat veteran, said when asked about Carlson’s attacks.
