Following the assassination attempt against former president Donald Trump, the United States Secret Service (USS) has advised the Republican to refrain from scheduling outdoor rallies.

Since the shooting during a rally in Butler, Pennsylvania, on July 13, Secret Service officials have raised concerns over large outdoor events organised by the 78-year-old Republican presidential nominee’s campaign, New York Post.

The Secret Service suggests that the rallies should be held in indoor settings instead, and it seems that the Republicans have taken these concerns seriously.

The media outlet also reported they are now in search of indoor venues for their forthcoming campaigns.

The campaign’s next two events are to be held in a multipurpose arena in Charlotte, NC, and a hockey arena in St Cloud, Minn.

The former president's first rally since the assassination attempt, which left him with a bloody ear, one rally-goer dead, and two others critically wounded, was held indoors as well, in Grand Rapids, Michigan.

Trump has held dozens of large outdoor rallies since launching his 2024 White House bid and hundreds since his first presidential campaign in 2016, with airports, fairgrounds, and parks frequently being utilised by the campaign to stage the events.

Although indoor rallies are costlier but they are safer because of the limited number of entrances and reduced line-of-sight issues, a Trump campaign official told the Washington Post.

Trump’s would-be assassin, 20-year-old Thomas Matthew Crooks, was lying on a rooftop just 130 yards away from the presidential candidate when he opened fire.

Former Secret Service Director Kimberly Cheatle resigned Tuesday after facing criticism that her agency did not adequately protect Trump at the Butler rally.

Secret Service officials had also repeatedly rejected Trump's request for additional security in the two years before the assassination attempt, citing a lack of resources.
