Some party leaders worry that a rise of pro-Trump candidates in the coming months could jeopardise the GOP's fight for control of Congress in 2022. While Trump remains a dominant force within his party, he is deeply unpopular among key segments of the broader electorate. He lost the last election by 7 million votes after alienating Republican-leaning suburban voters across the country.
In contrast to the mega rallies that filled sports arenas when Trump was president, he faced a crowd that organisers estimated at 1,200 seated at dinner tables inside the Greenville convention centre. Tens of thousands more followed along on internet streams.
Invited to the stage briefly during his remarks, Trump daughter-in-law and North Carolina native Lara Trump announced she would not run for the Senate because of family obligations.
"I am saying no for now, not no forever," Lara Trump said.
Minutes later, Trump announced his endorsement of loyalist Ted Budd in the crowded Republican primary, adding a slap at former Governor Pat McCrory, who has been critical of Trump's falsehoods about the 2020 election.
"You can't pick people who have already lost two races and do not stand for our values," Trump said.
McCrory served as the North Carolina governor from 2013 to 2017, but lost elections before and after his term.
The former president waited more than an hour to advance falsehoods about the 2020 election, which he described as "the crime of the century".
Since leaving the White House, Trump has regularly made baseless claims that the last presidential election was stolen. The claims have triggered a wave of Republican-backed voting restrictions in state legislatures across the country, even though Trump's cries of voting fraud have been refuted by dozens of judges, Republican governors and senior officials from his own administration.
Trump focused his early remarks on President Joe Biden, which he called "the most radical left-wing administration in history."
"As we gather tonight our country is being destroyed before our very eyes," he said.
Democratic National Committee spokesman Ammar Moussa took a shot at Trump in a statement released ahead of his speech.
"More than 400,000 dead Americans, millions of jobs lost, and recklessly dangerous rhetoric is apparently not enough for Republicans to break with a loser president who cost them the White House, Senate, and House," Moussa said.
