Elon Musk says he will attend Trump rally at Pennsylvania shooting site

Thomas Matthew Crooks, 20, injured the former president, killed rally attender Corey Comperatore and severely wounded two others as he got off clear shots with an assault rifle before he was killed by federal snipers.

Trump and his campaign have indicated they will turn the rally into a triumphant return for the former president, as well as a way to honor those who were killed or injured.

Trump has also faced ongoing death threats from Iran, which is also blamed for hacking into his campaign.

Trump has accused the Biden administration of intentionally denying security resources to help Kamala Harris, the US vice-president and his Democratic opponent in the November election, by preventing him from addressing large crowds, a signature of his political life.

Events have been canceled and moved around because the Secret Service lacked the resources to safely secure them. Even with the use of glass barricades to protect Trump on stage, there are concerns about holding additional rallies outdoors due to fears about drones.

Trump also now travels with a larger security footprint, with new traffic restrictions outside his Mar-a-Lago home in Florida, and a line of dump trucks and big guns on display outside Trump Tower in New York when he is staying there.
