“President Trump monitored the situation overnight at Mar a Lago [sic] alongside members of his national security team,” Leavitt posted to X. “The President spoke with Prime Minister [Benjamin] Netanyahu by phone,” Leavitt wrote, adding that Rubio notified a bipartisan group of lawmakers known as the “Gang of Eight” before the attack.

“Prior to the attacks, Secretary Rubio called all members of the gang of eight to provide congressional notification, and he was able to reach and brief seven of the eight members.”
