"I'm here today to express the nation's gratitude to Justice Stephen Breyer for his remarkable career in public service and his clear-eyed commitment to making our country's laws work for its people," Biden said, as Breyer stood behind him.

"Today, Justice Breyer announces his intention to step down from active service," Biden said.

Breyer, 83, is the oldest member on the nation's highest court.

Justice Breyer just issued a letter announcing his retirement.

"I intend this decision to take effect when the Court rises for the summer recess this year (typically late June or early July) assuming that by then my successor has been nominated and confirmed."
