The “Black Lives Matter” activist who came under fire from bloggers who said his birth certificate shows both his parents are white insisted Thursday the document is wrong.

“I have been told for most of my life that the white man on my birth certificate is not my biological father and that my actual biological father is a light-skinned black man,” Shaun King wrote on the political website Daily Kos.

“My mother and I have discussed her affair.”

Last June, Rachel Dolezal, an NAACP leader in Washington state who claimed she was biracial, was exposed as having two white parents.
