Former Secretary of State Hillary Clinton’s historic moment was rudely disrupted by a microphone glitch Tuesday night.

In Brooklyn, New York, Clinton took the stage to the pop song “Brave” by Sara Bareilles and raised her arms in triumph before beginning her speech claiming victory in the Democratic primary.

But the audio wasn’t working. After speaking several lines, members of the audience shouted, “We can’t hear you” before the microphone squealed as they turned it on.
