President Donald Trump has fired several White House National Security Council officials after he was urged by far-right activist Laura Loomer to purge staffers she deemed insufficiently loyal to his “Make America Great Again” agenda, several people familiar with the matter said Thursday.

The Trump administration has fired at least three officials at the National Security Council, with more firings expected, according to the BBC's US partner CBS News.

It is not clear why the staffers were removed from their roles, but CBS reports the decision followed a meeting between far-right activist Laura Loomer and President Donald Trump at the White House on Wednesday.

President Donald Trump reportedly fired multiple officials on his National Security Council shortly after he met with Laura Loomer in the Oval Office.

The president met with Loomer, a self-described “investigative journalist,” on Wednesday. Loomer has publicly accused Trump administration staffers of disloyalty and said there have been vetting failures at the NSC and elsewhere through various posts on X.

The United States dismissed Russia's allegation on Thursday that Washington was behind what it said was a drone attack on the Kremlin, saying Moscow's assertion was a lie.

The White House pinned the chaotic 2021 withdrawal from Afghanistan on the lack of planning from the previous administration and admitted it should have started evacuations sooner but stood by the decision to pull out of the country in a summary of an interagency report released Thursday.

The summary said that the administration was “severely constrained” by actions of former President Donald Trump’s administration, including the 2020 agreement Trump made with the Taliban to withdraw American troops by the spring of 2021.

The U.S. acknowledged its evacuations from Afghanistan in 2021 should have begun sooner — but largely blamed the Trump administration, according to a newly released National Security Council document outlining key moments.

Why it matters: The chaotic withdrawal from Afghanistan in summer 2021 — a pain point in Biden's presidency that's drawn bipartisan criticism — has also become a growing target of GOP-led congressional investigations.

The White House on Thursday released its review of President Biden's fumbled withdrawal from Afghanistan in 2021, dropping the long-awaited report days before the Easter holiday while former President Donald Trump's indictment dominates headlines. 

The Biden administration has “significant concerns” in some cases about China’s behavior when it comes to abiding by the international rules of the road, NSC spokesman John Kirby said Tuesday.

Chinese President Xi Jinping and Russian President Vladimir Putin are meeting on Tuesday in Moscow.

The White House on Tuesday said that they don’t have an indication that the three objects shot down by the U.S. military over the weekend were part of China’s spy program, noting though the difficulties with recovering the debris.
