Supreme Court Justice Stephen Breyer will retire at the end of the current court term. The 83-year-old is one of three sitting justices appointed by a Democratic president.
Since taking the White House and Senate, some Democrats have been calling for Breyer to step down while Democrats can confirm a new justice who can serve for decades.
Justice Ruth Bader Ginsberg died in September 2020, allowing former President Donald Trump to nominate 49-year-old Amy Coney Barrett to replace her before Trump left office.
Biden has not named a possible replacement.
