But after the assassination attempt, it was reported that she would now not only attend but speak at the conference.
Other speakers reportedly include Marjorie Taylor Greene, a Georgia congresswoman, Arizona Senate contender Kari Lake, Florida Governor Ron DeSantis, Dana White, head of the Ultimate Fighting Championship (UFC), former Fox News host Tucker Carlson, and Teamsters union general president Sean O’Brien.
RNC co-chair Lara Trump, the daughter-in-law of the former president, said celebrities will also be among the speakers.
Amber Rose, model, reality star, and former girlfriend of Kanye West, is expected to address the crowd.
But former stalwarts of the Republican party establishment, such as George W Bush, Mike Pence, and Mitt Romney, are not on the guest list.
former First Lady Melania Trump, who rarely makes public appearances, will attend the convention, according to US media.
Mrs Trump did not attend the 27 June debate between President Joe Biden and Trump. Neither did she attend her husband’s hush-money trial earlier this year.
While the former first lady has held Republican fundraisers in the past year, this would be her first major appearance of this election cycle.
Monday’s theme will be “Make America Wealthy Once Again”, Tuesday will be “Make America Safe Again”, Wednesday is “Make America Strong Again” and Thursday is “Make America Great Once Again”.
The party platform this year sits at 16 pages.
Some themes of Project 2025, a much longer think-tank proposal, are also likely to come up during the convention.
Project 2025 – from which Trump has distanced himself – calls for expanding presidential powers, eliminating thousands of civil servant posts, tax cuts, and dismantling the Department of Education.
A demonstration, the Coalition to March on the RNC, is scheduled for noon local time on Monday.
Organizers say they expect 5,000 protesters, with backing from 125 liberal activist groups around the country.
Omar Flores, the co-chair of the coalition, said on Friday: “Join us to fight against the Republicans’ racist and reactionary agenda, to stand with Palestine; to defend women’s, LGBTQ and reproductive rights; to defend and expand immigrant rights and to advocate for peace, justice, and equity.”
Milwaukee Mayor Cavalier Johnson said the city would ensure public safety is tantamount this week.
“A national special security event is the highest designation that you can get for a security event of its size and magnitude in the United States,” Mayor Johnson said.
