Speaking to CNN Capitol reporter Manu Raju, Republicans speculated Wednesday if one of the Montana Republicans is a plant for the Democratic Party.

Rep. Matt Rosendale (R-MT) is one of eight Republicans who voted to oust former Speaker Kevin McCarthy (R-CA). Rosendale is facing a primary from Tim Sheehy as he makes a bid for the U.S. Senate.

The National Republican Senatorial Committee is backing Sheehy over Rosendale.

“A lot of people are starting to wonder if Matt Rosendale is a plant from the Democrats,” an NRSC spokesperson told Raju.

“He is benefitting from millions of dollars in television ads from a Chuck Schumer-aligned super PAC and has been a great ally to Hakeem Jeffries and Nancy Pelosi in their efforts to take back the House,” the committee spokesperson added.

The millionaire Sheehy was recently profiled by "The Missoulian," revealing the Minnesotan graduated from a prep school near the Twin Cities. He's lived in Montana for a little under 10 years and describes himself as a "part-time rancher."

The winner of the race will face off against Montana native Sen. Jon Tester (D-MT), and other than being a Senator, he helps run his family's farm and butcher shop. A New York Times profile on him revealed he brings his own meat when he's in Washington.
