The White House skirted questions Tuesday regarding Sen. Joe Manchin’s (D-WV) decision to withhold an endorsement of President Joe Biden‘s 2024 reelection campaign.

Manchin, one of the most conservative Democrats in Congress, announced in 2023 that he would not seek reelection in 2024, fueling speculation that he himself might mount a third-party bid for the White House. However, Manchin announced in mid-February that he would not run for the presidency but said in an interview with CNN on Monday that he would not be endorsing Biden “right now.”
