Republicans raise alarm over US vulnerability to mass drone strikes after Israel-Iran conflict

White House press secretary Karoline Leavitt answers questions on U.S. strikes on Iran amid an intelligence leak about the operation. FIRST ON FOX: A group of House Republicans is demanding to know how the U.S. is ready to protect its own domestic assets in the event of a potential attack on the homeland. "We write to inquire with the U.S. Department of Defense (DOD) and the Department of Homeland Security (DHS) about the current state of drone attack countermeasures for our military installations, government buildings, embassies, and consulates, both domestic and abroad," the GOP lawmakers wrote in a letter. "The ongoing conflicts in Ukraine and the Middle East have demonstrated that large-scale, highly coordinated mass-drone attacks can be highly effective if the defender lacks adequate counter-drone defenses." An Iranian demonstrator holds an anti-American sign.
