Florida Governor Ron DeSantis has dropped out of the 2024 presidential race and endorsed Donald Trump.
He quit ahead of the Republican primary election in New Hampshire, where he was polling in the single digits.
Mr DeSantis was once considered a strong contender for the party’s nomination – but on Sunday he said he did not “have a clear path to victory”.
Nikki Haley, Mr Trump’s last remaining challenger, said she was the “only one” able to beat US President Joe Biden.
Ms Haley will go head-to-head with Mr Trump in New Hampshire on Tuesday, the second in a series of state-by-state contests to pick a Republican nominee for the November general election.
