Former President Bill Clinton’s doubled-down in his tense interaction with Black Lives Matter protesters today by praising his wife’s work to save lives in Africa, adding that it is “a place where Black Lives Matter.”

The jibe came in Philadelphia, where he’s stumping for his wife’s struggling 2016 campaign.

“I’ll tell you another story about a place where Black Lives Matter: Africa,” Clinton said.

“The other day, I started my day with a picture that was sent to me on my iPad of a little guy running a store—he wasn’t very tall—in Tanzania in Dar es Salaam. You know what his store said? All it was was little crafts. It said ‘The Hillary Clinton’ store. Now why did he say that? Because the first thing that she did as Secretary of State was triple the number of people in Africa whose lives we were saving from AIDS by going to all low-cost price drugs, the same thing she wants to do for the American people if we give her a chance.”

Earlier in the same back-and-forth with the Black Lives Matter protesters, Bill Clinton argued that they were defending criminals — specifically gang leaders — who encouraged black youths to take drugs like crack cocaine, and then engage in black-on-black violence that’s left so many young black men dead in inner cities across the country.

“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 street to murder other African American children—maybe you thought they were good citizens,” Bill Clinton said at the Hillary Clinton campaign rally in Philadelphia.
