The Congressional Black Caucus PAC will endorse Hillary Clinton on Thursday and help her campaign win over minority voters in upcoming primary contests, NBC News has confirmed.
Clinton already has a strong advantage over rival Bernie Sanders among black voters, and the CBC endorsement could help her solidify that support in states where the voting group plays a key role, like in the upcoming South Carolina Democratic primary.
The influential endorsement comes as the once clear frontrunner in the Democratic race is reeling from a 22-point loss to Sanders in New Hampshire.
Still remaining neutral is South Carolina Rep. James Clyburn, the third-ranking Democrat in the House and an influential voice in the Palmetto State. Though Clyburn originally said he would not endorse ahead of the South Carolina primary, he told NBC News' Andrea Mitchell he may change his mind.
"We'll be meeting with family and friends this weekend when I get down to South Carolina and I'll make some decision after that," Clyburn said on MSNBC. "I won't be making any endorsements today or this week."
