President Donald Trump confirmed that multiple employees within the National Security Council were fired Thursday, adding to National Security Advisor Mike Waltz's recent political woes that have snowballed since Democrats first slammed him over March's Signal chat leak.

The Pentagon's inspector general launched a probe into the Trump administration's use of Signal to discuss a planned strike on the Houthis in Yemen.

Senior Trump administration officials have been accused of using the third-party app to discuss highly sensitive national security information.

The Pentagon’s acting inspector general announced Thursday that he would review Defense Secretary Pete Hegseth’s use of the Signal messaging app to convey plans for a military strike against Houthi militants in Yemen.

The senior Republican and Democrat on the Senate Armed Services committee requested the probe after Hegseth disclosed sensitive on Signal.

The Pentagon’s inspector general will investigate whether Defense Secretary Pete Hegseth used the encrypted commercial app Signal to discuss classified information about a military strike in Yemen. Hegseth and other administration officials have denied any classified information was mentioned.

The inquiry will examine whether the Pentagon chief violated the agency’s standards for sharing classified information.

National Security Advisor Michael Waltz and a senior aide used personal Gmail accounts for government communications, according to a Washington Post report published yesterday.
