Republican frontrunner Donald Trump could be getting another endorsement from yet another political rival on Friday morning. Sources close to Ben Carson, the conservative favourite who quit the race for Republican presidential nomination, said that he is planning to throw his support behind Trump.

According to reports, the endorsement was finalised on Thursday morning, when Carson met with Trump at his luxury club Mar-a-Lago. The endorsement would be the most high-profile backing for Trump, after New Jersey Governor Chris Christie.

The endorsement will be announced at a press conference on Friday, which will also be held at a club in Palm Beach, Florida, the Washington Post reported.

On Thursday, Carson told the Fox News Radio that he is “certainly leaning” toward a particular candidate and showered Trump with compliments.

“There’s two Donald Trumps. There’s the Donald Trump that you see on television and who gets out in front of big audiences, and there’s the Donald Trump behind the scenes,” he said. “They’re not the same person. One’s very much an entertainer, and one is actually a thinking individual.”

Carson dropped out of the presidential nomination last week, as it was no longer possible for him to pull in the initial support that he managed to accrue. He told supporter he saw “no path forward.” He officially withdrew from the race in a speech at the Conservative Political Action Conference. While Trump swept the Republican primaries and lunged ahead by winning 15 primaries and bagging Republican’s top spot.

The Independent reported that though Trump already established a strong foothold in in the southern states, which mostly have evangelical voters, Carson’s backing would allow him to pick more support from the group.

Ever since he dropped out of the race, Carson has been based in his West Palm Beach residence, which is not too far from Trump’s Mar-a-Lago. This made Thursday’s meeting even easier.
