In a Facebook post, Darden admitted that he and his family received death threats since he elected to take on Holder's case last month.
"After centuries of a history of black men hung from trees without trial, or after the thousands of cases of black men tried, convicted and executed without counsel … I cannot understand why in 2019 some people would deny a black man his 6th Amendment right to counsel of his choice," he wrote. "Or why defending such a man should invite threats not only against me but against my children too."
In an interview with the Los Angeles Times on Friday, Darden explained why he initially took on Holder's case, saying: "I defend poor people — that's all I do. And he's definitely poor."
Darden is famously known for serving as the personal prosecutor in the OJ Simpson trial in 1995.
