Axios added that its source said several people had been fired, possibly as many as 10, including senior directors.
Brian Walsh, a director for intelligence and a former top staffer for Secretary of State Marco Rubio on the Senate Intelligence Committee, Thomas Boodry, a senior director for legislative affairs who previously served as Waltz's legislative director in Congress, and David Feith, a senior director overseeing technology and national security who served in the State Department during Trump's first administration were the three NSC officials let go, CNN reported.
The outlet added the firings followed conservative influencer Laura Loomer's Wednesday visit to the Oval Office.
"I woke up this morning to learn that there are still people in and around the West Wing who are LEAKING to the hostile, left-wing media about President Trump’s confidential and private meetings in the Oval Office," Loomer posted late-morning Thursday on X.
