Sen. Joe Manchin (D-WV) refused to rule out launching a third-party presidential run in 2024, saying that extremism is becoming a serious issue on both political sides.

Manchin made the remarks during a Sunday morning news show when asked about a recent report from The New York Times about a self-described bipartisan group, “No Labels,” that wants a third-party presidential candidate in 2024. Manchin sits at the top of the group’s list.

“No Labels has been moving and pushing very hard the centrist middle. Making commonsense decisions,” Manchin told Fox News host Shannon Bream. “People that basically expect us to do our job. And not put the political party ahead of the policy in our great country. That’s what we’ve seen happening. And there’s more noise and more extremism coming from the far left and the far right.”
