A preliminary report on the July 13 assassination attempt on former President Trump from the Senate Committee on Homeland Security and Governmental Affairs ripped into newly revealed missteps that went into the Secret Service's planning and execution of security at the event during which a spectator was killed, two others were seriously wounded and the GOP candidate was struck on the ear. Among the key failures, an agent inexperienced with drone equipment called a toll-free tech support hotline for help after a request ahead of time for additional unmanned assets was denied, according to a preliminary summary of findings made public Wednesday. According to the committee, he had just an hour of informal training with the device. "Multiple foreseeable and preventable planning and operational failures by USSS contributed to [Thomas] Crooks' ability to carry out the assassination attempt of former President Trump on July 13," the preliminary report read. "These included unclear roles and responsibilities, insufficient coordination with state and local law enforcement, the lack of effective communications, and inoperable C-UAS systems, among many others."

China on Monday announced export controls on some drones and drone-related equipment, saying it wanted to safeguard "national security and interests" amid escalating tension with the United States over access to technology. The restrictions on equipment, including some drone engines, lasers, communication equipment and anti-drone systems, will take effect on Sept. 1, the Commerce Ministry said. The controls also affect some consumer drones, and no civilian drones can be exported for military purposes, a ministry spokesperson said in a statement.
