Former Republican hopeful Ben Carson has confirmed his support for his former rival and front-runner Donald Trump in the US presidential race.
He made the endorsement at a joint news conference in Florida with Mr Trump, ahead of primaries there on Tuesday.
The winner of the Republican nomination will face Hillary Clinton or Bernie Sanders for the Democrats, in November.
Mr Carson is the second former candidate to endorse Mr Trump after New Jersey Governor Chris Christie.
A retired neurosurgeon, Mr Carson was an early favourite but dropped out last week after failing to gain significant popular support.
The endorsement came a day after an elderly white man was charged with assault for allegedly punching a young protester during a rally for Mr Trump in North Carolina on Wednesday.
Video footage taken by bystanders shows John McGraw, 78, apparently hitting 26-year-old Rakeem Jones as he was being escorted away by police.
