In one of the more touching moments from President Donald Trump’s State of the Union address on Tuesday night, the entire chamber interrupted the speech to sing happy birthday to a Holocaust survivor in attendance.

That survivor, Judah Samet, also narrowly escaped death last fall when a gunman killed 11 people at his Pittsburgh synagogue.

When Trump noted that it was Samet’s 81st birthday, the chamber couldn’t help themselves but erupt in song while Trump mimicked a conductor.
