State Department Spokesperson Tammy Bruce found out President Donald Trump had appointed Secretary of State Marco Rubio acting National Security Adviser from a reporter. During a press briefing Thursday, a journalist notified Bruce of Rubio’s appointment and asked if she knew how long he would be serving in his new gig. “It is clear that I just heard this from you,” Bruce replied. “I have some insights as to the potential of certain things that might happen,” she continued, warning against “drawing conclusions or speculating about what may occur.” Trump announced on Truth Social earlier Thursday that former security adviser Mike Waltz would now serve as ambassador to the United Nations, while Rubio would fill in as his successor on an interim basis. “Things don’t happen until the president says they’re going to happen,” Bruce added. Waltz is the first senior casualty of the second Trump administration. His future as national security adviser had been in doubt since his spectacular Signal chat blunder in March, in which he inadvertently added a journalist to a group of top Trump officials discussing military operations in Yemen.
