Here are the highlights from the 2024 campaign trailNBC News projected former President Donald Trump the winner of New Hampshire's Republican presidential primary against former U.N. Ambassador Nikki Haley yesterday, a victory driven by dominant support from self-identified GOP voters.Trump is the first nonincumbent GOP candidate to win both Iowa and New Hampshire. He is calling for Haley to end her race so the Republican Party can coalesce behind him.Haley, who performed well among self-identified moderates, has vowed that the race is not over, and she will travel to New York City on Monday and Tuesday to court Wall Street donors at multiple fundraisers, according to two campaign sources.President Joe Biden received the endorsement of the United Auto Workers union. The union's endorsement could be key in the battleground state of Michigan, which narrowly went for Biden in 2020 after backing Trump by a razor-thin margin in 2016.
