Anti-Israel protesters interrupted former House Speaker Nancy Pelosi’s (D-CA) appearance on The Late Show with Stephen Colbert during a discussion on the hostage situation between Israel and Hamas.

Pelosi appeared on the show Tuesday night to promote her new book, The Art of Power, during which she recounted how she watched President John F. Kennedy’s inauguration speech in 1961. In this speech, Kennedy said that nations ought to ask the United States what they can do to achieve the “freedom of mankind,” with Pelosi arguing this is what President Joe Biden has sought to achieve with countries like Israel.
