The first day of the 2024 Republican National Convention brought a flurry of newsworthy happenings from Milwaukee, Wisconsin, kicking off the week-long event with a bang.
Here are five of the biggest moments from the day.
Donald Trump's spectacular arrival
Former President Trump made his first public appearance since the assassination attempt on Monday.
The stadium in Milwaukee erupted in thunderous applause and cheers for a long period as Trump made his entrance. Approval for the former president has soared in the days since the assassination attempt, and his welcome at the Republican National Convention was a sign that the GOP was united behind its candidate.
J.D. Vance becomes vice president
Speculation about who Trump would choose as his running mate had been rife for months as the former president considered his options.
Trump, who frequently mentioned popular candidates but never made any promises, leaned into the competitive spirit, and his choice of Vance kept tensions high until the final hour.
Vance is expected to begin campaigning as soon as the Republican National Convention ends this week.
Union leader calls Trump a 'tough guy'
Shortly after Trump arrived at the arena in Milwaukee, Sean O'Brien, president of the International Federation of Trucking Associations, described Trump as a “tough bastard” following the assassination attempt on the 2024 Republican presidential candidate.
O'Brien's presence marked an unusual unity between Republicans and labor unions, and many commentators said it was a sign of a new Republican Party.
President Trump details phone call with Biden after assassination attempt
Trump revealed for the first time details of a phone call he had with President Biden just hours after suspect Thomas Matthew Crooks attempted to assassinate him.
Biden said Saturday that he spoke briefly with Trump after the shooting but did not provide details. Trump said Biden “couldn't have been nicer” during the conversation, adding that it was “good, short and respectful.”
Elon Musk donates $45 million a month to Trump PAC
Billionaire Elon Musk did not attend the Republican National Convention, but he has announced ambitious plans to support the Trump campaign in the final months of the race.
Musk has said he will donate $45 million a month to the pro-Trump PAC America. Musk endorsed Trump after the assassination attempt this weekend in Butler, Pennsylvania. He had previously spoken favorably of the former president but had not formally endorsed him.
