A person in the crowd at President Donald Trump’s inauguration shouted “LOCK HER UP!” as Vice President Mike Pence was being sworn in.

Supreme Court Justice Clarence Thomas had just finished swearing Pence in, and as the crowd died down, a single voice screamed out the line. The crowd also chanted “drain the swamp,” a campaign promise by Trump to clear out career politicians and and elites in Washington, D.C.

Former Democratic nominee Hillary Clinton is in attendance at the inauguration.
