Joe Biden’s summer is starting to look brighter. With widespread media reports that Justice Stephen Breyer will retire from the U.S. Supreme Court at the end of the current term, the President may have an opportunity to take a major step in his goal to build a more diverse federal judiciary. Biden pledged on the campaign trail that he would nominate the first Black woman to the Supreme Court, and on Wednesday—before the Supreme Court or the White House publicly confirmed Breyer’s plans—Democrats were already pressuring Biden to keep his promise. The calls came from progressive groups and sitting lawmakers alike.
