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.

Trump’s address, the longest convention speech 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.

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.
