US Republican, Ben Carson, has withdrawn his bid to emerge as the party’s presidential candidate for the 2016 election.
Mr Carson, a retired neurosurgeon, had been a front-runner, but his campaign stalled in recent months after he performed badly on foreign affairs and questions about his background story.
He has not said which of the remaining four candidates he plans to endorse in the race for the republican nomination.
Mr Carson had earned only eight delegates before his decision to drop out from the nomination race.
Republicans in four states – Kansas, Kentucky, Louisiana and Maine – would go to the polls on Saturday.
Earlier on Friday, Mr Carson was announced as a new Chairman of My Faith Votes – a group set up to encourage Christians to vote in elections.
Mr Carson had a poor upbringing in Detroit but made it to Yale before a brilliant medical career.
