Sen. Joe Manchin, D-W.Va., on Sunday endorsed the re-election campaign of his Republican colleague Lisa Murkowski of Alaska, who faces a tough challenger this year supported by former President Donald Trump.

"I'm endorsing my dear friend Lisa Murkowski," Manchin said on CNN's "State of the Union." "Alaska could only be so lucky to have her continue to serve them."

Murkowski returned the favor, saying she will endorse Manchin, who is up for re-election in 2024, if he decides to run.

In a rare show of bipartisanship, Sens. Joe Manchin and Lisa Murkowski appeared in a joint TV interview on Sunday and exchanged endorsements.

Manchin, a Democrat from West Virginia, and Murkowski, a Republican from Alaska, appeared on CNN's "State of the Union," during which Manchin endorsed her and called her a "dear friend."

Democratic Sen. Joe Manchin and Republican Sen. Lisa Murkowski endorsed each other Sunday during a joint TV interview — as Manchin defended his opposition of President Biden’s $2 trillion social spending bill, saying he’s “not a Washington Democrat.”

The lawmakers put up a bipartisan front during their appearance on CNN’s “State of the Union” ahead of their upcoming re-election races.

“I’m endorsing my dear friend Lisa Murkowski. Alaska could only be so lucky to have her continue to serve them,” Manchin, of West Virginia, said on the show.
