Livestream: President Biden hosts NBA champion Celtics at the White House

The Boston Celtics traveled to the White House Thursday to meet with President Joe Biden and celebrate the franchise’s 18th NBA championship.

The Celtics flew to Washington, D.C., on Wednesday and will stay in town for a game against the Washington Wizards on Friday.

It is a longstanding tradition for American sports teams to meet with the president after winning a championship. The first visit from an organized sports team occurred in 1865, when President Andrew Johnson met with the Brooklyn Atlantics and Washington Nationals amateur clubs. President Ulysses S. Grant hosted the first professional team, the Cincinnati Red Stockings, in 1869.

John F. Kennedy was the first president to host an NBA champion, when the Celtics visited in 1963.
