U.S. President Donald Trump?s national security adviser Mike Waltz is being forced out of his job, four people briefed on the matter said on Thursday, in the first major shakeup of Trump?s inner circle since he took office in January.

Waltz?s deputy, Alex Wong, an Asia expert who was a State Department official focused on North Korea during Trump?s first term, is also leaving his post, two people told Reuters.

Waltz, a 51-year-old former Republican lawmaker from Florida, faced criticism inside the White House when he was caught up in a March scandal involving a Signal chat among top Trump national security aides.

The national security adviser is a powerful role that does not require Senate confirmation. It was not immediately clear who would take over from Waltz. The National Security Council did not immediately reply to a request for comment.

Sources said the options included U.S. special envoy Steve Witkoff, who has been involved in Russia-Ukraine diplomacy as well as the Middle East, and Deputy Secretary of State Christopher Landau.

Secretary of State Marco Rubio could assume the position on a temporary basis while a permanent selection is settled upon, sources said.

The Waltz ouster caps a month of personnel turmoil within Trump?s national security establishment. Since April 1, at least 20 NSC staffers have been fired, the director of the National Security Agency has been dismissed and three high-ranking Pentagon political appointees have been shown the door.

The purges have seriously hurt morale in some areas of the national security establishment, according to several officials within or close to the administration. Some elements of the government are low on relevant national security expertise and in some cases it has proven difficult to attract high-level talent, the officials added.

The NSC Is the main body used by presidents to coordinate security strategy, and its staff often make key decisions regarding America?s approach to the world?s most volatile conflicts.

Waltz was blamed for accidentally adding the editor of The Atlantic magazine to a private thread describing details of an imminent U.S. bombing campaign in Yemen. The Atlantic reported on the mishap.

At a subsequent Cabinet meeting with Waltz in the room, Trump expressed his preference for holding such conversations in a secure setting, a clear sign of his displeasure. But he and others in the White House publicly expressed confidence in Waltz at the time. Waltz also attended Trump?s televised Cabinet meeting on Wednesday.

WAVE OF FIRINGS

The NSC that Waltz will leave behind has been thinned by dismissals in recent weeks.

The bloodletting began a month ago, when Laura Loomer, a right-wing conspiracy theorist, handed Trump a list of individuals in the NSC she deemed to be disloyal during a meeting at the White House. Following that meeting, four senior directors were released.

Those four senior directors ? who oversaw intelligence, technology, international organizations and legislative affairs, respectively ? had a long history in conservative policymaking and no apparent animosity toward Trump, leaving colleagues puzzled by their dismissals, according to two people with direct knowledge of the matter.

Some NSC staffers were upset that Waltz did not more forcefully defend his staff, those people said.

Since then, more than 20 additional NSC staffers of various profiles have been let go, typically with no notice, the people said.

In recent weeks, multiple officials have declined positions at the NSC amid the ongoing personnel upheaval, according to two sources with direct knowledge of the matter. Some areas of the council are now lightly staffed, with both the Latin America and Africa sections lacking permanent senior directors as of last week.

The Signal controversy was not the only mark against Waltz in Trump?s eyes, sources said.

A person familiar with the Cabinet?s internal dynamics said Waltz was too hawkish for the war-averse Trump and was seen as not effectively coordinating foreign policy among a variety of agencies, a key role for the national security adviser.

Another source said Trump wanted to get to the 100-day mark in his term before firing a cabinet-level official.

Waltz?s ouster could be of concern to U.S. partners in Europe and Asia who have seen him as supportive of traditional alliances such as NATO and tempering more antagonistic views toward them from some other Trump aides, according to one foreign diplomat in Washington who spoke on condition of anonymity.

Democrats who were outraged about the Signal scandal welcomed the news about Waltz.
