 This is an NBC News Radio special report. The Republican National Convention. I'm Michael Kastner. Donald Trump is officially the Republican Party's nominee for president. Trump accepted the nomination last night at the RNC in Milwaukee and gave his first speech since Saturday's assassination attempt at a campaign rally in Pennsylvania. He said after a bullet grazed his ear at the rally, he raised his fist to show supporters he was okay when he mouthed the words, fight, fight, fight.
