Florida governor Ron DeSantis has dropped out of the GOP Presidential race and has given his full support to former President Donald Trump.
He quit ahead of the Republican primary election in New Hampshire, where he was polling in the single digits.
Nikki Haley, Mr Trump’s last remaining challenger, said she was the “only one” able to beat US President Joe Biden.
She would go head-to-head with Mr Trump in New Hampshire on Tuesday in a contest to pick the Republican nominee for the forthcoming elections.
In a nearly five-minute long video on X, formerly Twitter, released on Sunday afternoon, Mr. DeSantis said his campaign had “left it all out on the field”.
“If there was anything I could do to produce a favorable outcome – more campaign stops, more interviews – I would do it,” he added, as he ended his seven-month campaign.
The Florida governor said he was endorsing Mr Trump, who is the clear frontrunner after winning the first contest in Iowa with 51% of the vote.
“I signed a pledge to support the Republican nominee, and I will honor that pledge,” Mr. DeSantis said.
After Mr DeSantis’ announcement, the Trump campaign called on all Republicans to rally behind Mr Trump.
