President Donald Trump has ousted his national security adviser, Mike Waltz, and appointed Secretary of State Marco Rubio as interim replacement — marking the first major reshuffle since Trump returned to office.⁣ ⁣ Trump praised Waltz’s work and said he will nominate him as the next U.S. ambassador to the United Nations.⁣ ⁣ Rubio now holds both top roles — the first person since Henry Kissinger in the 1970s to serve as secretary of state and national security adviser at the same time.⁣ ⁣ At a White House event, Trump said, “When I have a problem, I call Marco. He gets it solved.”⁣ ⁣ Waltz had recently come under fire after being linked to a March scandal involving a Signal chat among top national security aides.⁣ ⁣ #Trump #DonaldTrump #US #signalgate #Rubio
