Ben Carson will endorse his former rival Donald Trump on Friday, the real estate mogul announced during Thursday evening's debate.
The Washington Post first reported Carson's endorsement. Trump has scheduled a 9 a.m. ET press conference at his Mar-A-Lago resort in Palm Beach, Fla., where the retired neurosurgeon is expected to make his endorsement official.
Carson's support comes just a week after he officially ended his campaign. The famed African-American doctor had a surge of support last fall, but faltered after terrorist attacks exposed his weaknesses on foreign policy.
