Potential shift in White House's national security leadership: Marco Rubio could be the new choice, or President Trump might opt for no change.
Here's a fresh take on your input:
In the nation's capital, holding more than one high-profile job simultaneously has become a new norm for politician Marco Rubio. The high-stakes game of musical chairs now has Rubio acting as Secretary of State, Acting Administrator of the U.S. Agency for International Development, Acting Head of the National Archives and Records Administration, and as of recent, the acting National Security Adviser.
With President Donald Trump announcing that Michael Waltz, under scrutiny since the Signal chat leak, would be stepping down to stand as the U.S. ambassador to the United Nations, Rubio was tapped for the interim National Security Adviser role more than a month ago. However, the decision was deferred until Trump had finally grown tired of Waltz.
There's a strong possibility that Trump holds onto Rubio in the National Security Adviser position for good, according to sources familiar with the matter. The president seems in no rush to find a replacement.
A senior State Department official stated, "The president has assembled an incredibly talented team that is fully committed to putting America and Americans first. Secretary Rubio looks forward to serving as his interim National Security Advisor while ensuring the mission-critical work at the State Department continues uninterrupted."
Two sources said Waltz's departure was brewing for weeks following revelations published by The Atlantic on March 24 stating that Waltz had created a group chat with top administration officials on the private messaging app Signal and inadvertently added Jeffrey Goldberg, the editor-in-chief of the magazine[1]. However, there was no immediate push to fire Waltz for fear of handing critics a quick victory. Instead, he was sent off to the United Nations.
