WASHINGTON -- Democratic Senator Joe Manchin from West Virginia on Sunday supported the reelection campaign his Republican colleague, Sen. Lisa Murkowski Alaska. Murkowski is up against a formidable challenger this election year. He was previously supported by President Donald Trump.

Manchin stated, "I am endorsing Lisa Murkowski," on Sunday's CNN's State of the Union. "Alaska couldn't be more fortunate to have her continue serving them."

Murkowski said she would endorse Manchin if he chooses to run.

In a joint interview, the two moderate senators appeared together on the show to promote bipartisanship after President Joe Biden's infrastructure agreement was passed and amid preliminary talks to amend the Electoral Count Act.

Manchin stated, "It is hypocritical to work with someone day in, day out, and then when they're going through cycle, you're supposed be against them because their R or D is by their name."

Trump supported Kelly Tshibaka's campaign to unseat Murkowski in June. He gave his support to an outsider candidate, who had echoed his false claims about election fraud. He endorsed Kelly Tshibaka just months after Murkowski was convicted for inciting the Jan. 6 Capitol riot.

Murkowski and Manchin both crossed party lines on many legislative issues, drawing outrage from their own caucus. While the Alaska Republican opposed a Republican effort to repeal Obamacare in 2019, a West Virginia Democrat stated last month that he would not support President Joe Biden’s signature Build back Better Act.

Murkowski could be in a tough race after Trump endorsed her challenger. Murkowski announced her reelection campaign in Nov. In the 2020 presidential election, Alaska was won by the former president.
