The Secret Service and the safety of the candidates have become a significant concern following last month’s assassination attempt against former President Donald Trump, as well as a plot by the Iranians to kill him and anyone else from his first administration who was involved in the January 2020 assassination of Iranian military Gen. Qassem Soleimani.

“The Department of Defense recently received a request for assistance from the Department of Homeland Security for additional military support capabilities to be afforded to major presidential and vice presidential candidates,” deputy Pentagon press secretary Sabrina Singh said. “The secretary of defense approved the request and directed the commander of U.S. Northern Command to plan, provide, and execute increased support to the United States Secret Service at various locations across the United States during the 2024 election campaigns.”

Singh announced both the DHS’s request and Austin’s approval on Thursday but did not provide details for what resources would be provided. It’s also unclear which personnel would be involved.

The DOD will provide protective support that will continue through Election Day, as well as through the inauguration for the president-elect and vice president-elect.

Thomas Matthew Crooks, a 20-year-old Pennsylvania native, scaled a building less than 200 yards from where Trump was speaking in Butler, Pennsylvania, and fired multiple shots at him. Crooks grazed the president’s ear, killed a spectator, and injured two others. Law enforcement officers shot and killed him immediately after he fired at the former president.
