Black Lives Matter protestors repeatedly interrupted a Bill Clinton campaign rally in Philadelphia on Thursday.

Shortly after former Pennsylvania Gov. Ed Rendell introduced the ex-president to the stage a group of protestors began chanting in the back of the room and would not stop chanting even as Clinton asked them to stop. Although his wife Hillary Clinton has often dealt with Black Lives Matter protestors at campaign events, this was one of Bill Clinton's first encounters and he became easily agitated.

"I don't know how you would characterize the gang leaders who got 13-year-old kids hopped up on crack and sent them out into the streets to murder other African Americans. Maybe you thought they were good citizens, but she didn't, she didn't," Clinton said referring to his wife. "You are defending the people who killed the lives you say matter. Tell the truth, tell the truth."

The 42nd president was extremely popular among African-American voters during his time in office, a fact he reminded the crowd as the protesters grew louder.

Clinton added, "When somebody won't hush and listen to the truth they're afraid of the truth. Don't you be afraid of the truth."
