The crowd at the Conservative Political Action Conference brought back an old stand-by from President Donald Trump’s campaign during his speech Friday morning: chants of “lock her up!” at the mention of Hillary Clinton.

Trump brought up Clinton’s infamous “basket of deplorables” comment during the speech and the crowd began to boo and break out into the chant.
