Former US Presidential candidate Dr Ben Carson has officially endorsed Donald trump’s campaign.

Dr Carson made the announcement early on Friday. He hinted of the endorsement on Thursday.

The former neurosurgeon’s endorsement comes as the latest in a number of high profile endorsements.

Previously Trump was endorsed by New Jersey Governor Chris Christie, who has since faced calls to step down, not to mention ridicule for looking unengaged during a Trump rally.

Retired neurosurgeon Carson, who has made a string of anti-LGBT comments, made the announcement in a statement on his website last week that he was suspending his campaign, saying he did not see how it could continue.

Carson has made a stunning number of homophobic and transphobic statements as he has campaigned for the Republican presidential nomination, including saying that transgender people in the millitary would be a “distraction” and a “social experiment” that the millitary did not need.

He has also stated that he would consider reintroducing don’t ask don’t tell and that he thinks that LGBT people caused the fall of Rome.

Carson has repeatedly been forced to apologise when caught making overtly homophobic comments – apologising after he was caught comparing gay people to paedophiles, and again apologising after he was caught claiming that prisons ‘prove’ being gay is a choice.

His repeated humiliations have not dissuaded him, however – just last year he compared gay couples to conjoined twins.

Trump has rallied against equality in recent weeks, telling old Fox News he would “strongly consider” a plot to overturn same-sex marriage, and telling evangelical leaders they can “trust” him to protect “traditional marriage”.

However, he has tied himself in a knot by simultaneously telling a lesbian journalist that he would “move forward on LGBT rights” – and when challenged attempted to maintain both viewpoints simultaneously.
