Kevin McCarthy speaks to Fox News (screen grab)

On Thursday, according to CNN's Jake Tapper, House Minority Leader Kevin McCarthy (R-CA) is refusing to acknowledge that Joe Biden won the presidential election, saying that he doesn't "know" whether Biden will be president next year.

McCarthy joins the ranks of several prominent Republicans who are not yet acknowledging Biden as the winner, even though he has a functionally recount-proof lead in several key states including Arizona, Georgia, Pennsylvania, and Nevada.

President Donald Trump has likewise refused to concede the election or begin the transition process, and his campaign is still in court with several challenges to various ballots.
