MILWAUKEE (AP) — Donald Trump, somber and bandaged, accepted the GOP presidential nomination on Thursday at the Republican National Convention in a speech that described in detail the assassination attempt that could have ended his life just five days earlier before laying out a sweeping populist agenda, particularly on immigration.

The 78-year-old former president, known best for his bombast and aggressive rhetoric, began his acceptance speech with a softer and deeply personal message that drew directly from his brush with death. Moment by moment, the crowd listening in silence, Trump described standing onstage in Butler, Pennsylvania, with his head turned to look at a chart on display when he felt something hit his ear. He raised his hand to his head and saw immediately that it was covered in blood.

“If I had not moved my head at that very last instant, the assassin’s bullet would have perfectly hit its mark,” Trump said. “And I would not be here tonight. We would not be together.”

Trump’s address, among the longest convention speeches in modern history at just under 93 minutes, marked the climax and conclusion of a massive four-day Republican pep rally that drew thousands of conservative activists and elected officials to swing-state Wisconsin as voters weigh an election that currently features two deeply unpopular candidates. Sensing political opportunity in the wake of his near-death experience, the often bombastic Republican leader embraced a new tone he hopes will help generate even more momentum in an election that appears to be shifting in his favor.

“The discord and division in our society must be healed. We must heal it quickly. As Americans, we are bound together by a single fate and a shared destiny. We rise together. Or we fall apart,” Trump said, wearing a large white bandage on his right ear, as he has all week, to cover a wound he sustained in the Saturday shooting. “I am running to be president for all of America, not half of America, because there is no victory in winning for half of America.”

While he spoke in a gentler tone than at his usual rallies, Trump also outlined an agenda led by what he promises would be the largest deportation operation in U.S. history. He repeatedly accused people crossing the U.S.-Mexico border illegally of staging an “invasion.” Additionally, he teased new tariffs on trade and an “America first” foreign policy.

Trump also falsely suggested Democrats had cheated during the 2020 election he lost — despite a raft of federal and state investigations proving there was no systemic fraud — and suggested “we must not criminalize dissent or demonize political disagreement,” even as he has long called for prosecutions of his opponents.

Trump barely mentioned Democratic President Joe Biden, often referring only to the “current administration.”

The RNC ends at an uncertain moment in the race

With less than four months to go in the contest, major changes in the race are possible, if not likely.

Trump’s appearance comes as the 81-year-old Biden clings to his party’s presumptive nomination in the face of unrelenting pressure from key congressional allies, donors and even former President Barack Obama, who fear he may be unable to win reelection after his disastrous debate.

Long pressed by allies to campaign more vigorously, Biden is instead in isolation at his beach home in Delaware after having been diagnosed with COVID-19.

Hours before the balloons were scheduled to rain down on Trump and his family inside the convention hall, Biden deputy campaign manager Quentin Fulks appeared nearby in Milwaukee and insisted over and over that Biden would not step aside.

“I do not want to be rude, but I don’t know how many more times I can answer that,” Fulks told reporters. “There are no plans being made to replace Biden on the ballot.”

Strength on the program

Thursday’s RNC program seemed designed to project strength and masculinity in an implicit rebuke of Biden.

Ultimate Fighting Championship President Dana White called Trump “a real American bad ass.” Kid Rock performed a song with the chorus, “Fight, fight!,” echoing the word Trump shouted on stage in Pennsylvania as Secret Service agents helped him off the stage. And wrestling icon Hulk Hogan described the former president as “an American hero.”

Hogan drew a raucous response when, standing on the main stage, he ripped off his shirt to reveal a red Trump-Vance “Make America Great Again” shirt.

“As an entertainer, I try to stay out of politics,” Hogan said as he briefly broke character. “I can no longer stay silent.”

Like many speakers during the convention, former Fox News host Tucker Carlson suggested that recent events were divinely inspired and that he wondered “if something bigger is going on.”

“I think it changed him,” Carlson said of the shooting, praising Trump for not lashing out in anger afterward.

“He did his best to bring the country together,” Carlson added. “This is the most responsible, unifying behavior from a leader I’ve ever seen.”

Former first lady Melania Trump and Ivanka Trump, the president’s elder daughter and former senior adviser, joined Trump in the convention hall ahead of his speech, making their first appearances there. Neither woman spoke.

Republicans leave their convention united

The convention has showcased a Republican Party reshaped by Trump since he shocked the GOP establishment and won over the party’s grassroots on his way to the party’s 2016 nomination. Rivals Trump has vanquished — including Sens. Ted Cruz of Texas and Marco Rubio of Florida, former U.N. Ambassador Nikki Haley and Florida Gov. Ron DeSantis — put aside their past criticisms and gave him their unqualified support.

Even his vice presidential pick, Ohio Sen. JD Vance, Trump’s choice to carry his movement into the next generation, was once a fierce critic who suggested in a private message since made public that Trump could be “America’s Hitler.”

Security was a major focus in Milwaukee in the wake of Trump’s near-assassination. But after nearly four full days, there were no serious incidents inside the convention hall or the large security perimeter that surrounded it.

The Secret Service, backed by hundreds of law enforcement officers from across the nation, had a large and visible presence. And during Trump’s appearances each night, he was surrounded by a wall of protective agents wherever he went.

Meanwhile, Trump and his campaign have not released information about his injury or the treatment he received. The former president on Thursday described his story of surviving the attack — and vowed he would not talk about it again.

“I’m not supposed to be here tonight,” Trump told the packed convention hall. The crowd of thousands, which was listening in silence, shouted back, “Yes, you are.”
