It was…
…none other than Al Sharpton.
From Ken Lovett, one of the only writers at the
New York Daily News worth a lick:
“A lot of folks don't believe in public policy. But this is not their holiday. This is Dr. King's day. This ain't your birthday. And Dr. King was about public policy. On your birthday we'll eat chitlins and watermelon and drink some sweet iced tea because that's what you do. But on his birthday, on his holiday, we do what King does. We're going to march.We're marching about minimum wage. Fifteen dollars an hour minimum wage.”
