U.S. officials and members of Congress say President Donald Trump has abruptly fired the director of the National Security Agency.

The problem isn’t just that the president has fired national security officials without cause, it’s also why he made these drastic moves.

U.S. President Donald Trump fired General Timothy Haugh as director of the National Security Agency, in a national security purge that sources said on Friday included more than a dozen staff at the White House national security council.

Several White House National Security Council officials were fired on Thursday in the first major purge of Trump's second term, Reuters reported.

The Washington Post reported late Thursday that Gen. Tim Haugh and his civilian deputy at the NSA, Wendy Noble, had been dismissed from those roles.

Loomer met with Trump and other top White House officials in the Oval Office on Wednesday, two sources familiar with the meeting told NBC News.

The dismissal of Gen. Tim Haugh comes after the president let go of several National Security Council officials.

Gen. Timothy Haugh, who was chief of U.S. Cyber Command in addition to leading the NSA, was fired by the Trump administration Thursday night.
