WASHINGTON (AP) — President Donald Trump said Thursday that he’s fired “some” White House National Security Council officials, a move that comes a day after far-right activist Laura Loomer raised concerns directly to him about staff loyalty.

Trump downplayed Loomer’s influence on the firings. But Loomer during her Oval Office conversation with Trump urged the president to purge staffers she deemed insufficiently loyal to his “Make America Great Again” agenda, according to several people familiar with the matter. They all spoke on the condition of anonymity to discuss the sensitive personnel manner.

“Always we’re letting go of people,” Trump told reporters aboard Air Force One as he made his way to Miami on Thursday afternoon. “People that we don’t like or people that we don’t think can do the job or people that may have loyalties to somebody else.”

The firings by Trump of NSC staff come at a tumultuous moment for Trump and his national security team. His national security adviser Mike Waltz, continues to fight back calls for his ouster after using the publicly available encrypted Signal app to discuss planning for the sensitive March 15 military operation targeting Houthi militants in Yemen.

Trump has said he stands by Waltz, who traveled to Florida with the president on Thursday for a dinner event ahead of the LIV Golf tournament in Miami.
