Senate Majority Leader Mitch McConnell alerted House Minority Leader Kevin McCarthy Tuesday morning that he would congratulate President-elect Joe Biden for winning the Electoral College vote.

But, but, but: McCarthy is refusing to do the same, and a group of 26 incoming GOP House members sent House Speaker Nancy Pelosi a letter asking her to investigate alleged voter fraud.

Why it matters: While the Senate majority leader is trying to return a sense of equilibrium to his chamber, McCarthy — who’s already plotting his run for House speaker in 2022 — is refusing to do anything that may upset President Trump.
