"Mitch, I don’t want to hurt your reputation, but we really are friends," Biden said with a laugh. The president noted that this was nothing new, and "not an epiphany" he was having.

The two men spoke to each other on Tuesday about the nomination, which will be for the Supreme Court seat that will be vacant upon the retirement of Justice Stephen Breyer, expected to take effect at the conclusion of the current court term in June or July.

So far, all Biden has said about whom he will pick is that they will be a Black woman and "someone with extraordinary qualifications, character, experience, and integrity."

According to a spokesperson for McConnell, the minority leader told the president that he believes any selection should have an originalist and textualist approach to interpreting the Constitution, which is typical of more conservative jurists. McConnell also emphasized the significance of having a potential justice who values judicial independence.
