Gen. Timothy Haugh, who is the director of the National Security Agency and also heads United States Cyber Command, and his civilian Deputy Director Wendy Noble, were both removed from their positions, a U.S. official confirmed to ABC News.

Connecticut Rep. Jim Himes, who is the ranking Democrat on the House Permanent Select Committee on Intelligence, requested an explanation as to why Haugh has been removed. “I am deeply disturbed by the decision to remove General Haugh as Director of the National Security Agency. I have known General Haugh to be an honest and forthright leader who followed the law and put national security first—I fear those are precisely the qualities that could lead to his firing in this Administration,"he said.

“The Intelligence Committee and the American people need an immediate explanation for this decision, which makes all of us less safe,” Himes said Thursday evening.

The Washington Post was the first to report the removals of both Haugh and Noble.

Entire CDC labs studying outbreaks of sexually transmitted diseases and hepatitis were shuttered this week as part of the sweeping layoffs at the Department of Health and Human Services, two people familiar with the cuts told ABC News.

The lab studying STDs, with about 30 full-time employees and several fellows, led a high-impact program monitoring drug resistance to gonorrhea, a disease notorious for its resistance to many antibiotics, according to someone with knowledge of the lab’s work.

The lab collaborates with state and local labs across the country in its surveillance of STD outbreaks.

“The rest of this operation can’t operate without the lab,” the person familiar with the lab’s work said.

CBS News first reported the layoffs at the two labs.

HHS Secretary Robert F. Kennedy Jr. told ABC News’ Cheyenne Haslett Thursday that he will reinstate some of the laid-off employees, but the people who spoke to ABC News about the STD and hepatitis labs had no indication workers at the lab would be among the reinstated.

A coalition of attorneys general from 19 states have filed a lawsuit against President Donald Trump’s recent executive order on election administration, alleging that the order is unconstitutional.

In the suit, which names Trump and other administration members as plaintiffs, the attorneys general argue that the suit is unconstitutional because, among other reasons, it takes away the states’ rights to regulate elections themselves and “treats Plaintiff States as mere instruments of the President’s policy agenda.”

The states that are part of this suit are Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Massachusetts, Maryland, Michigan, Minnesota, Nevada, New Jersey, New Mexico, New York, Rhode Island, Vermont, and Wisconsin.

The Senate on Thursday confirmed Dr. Mehmet Oz as Trump’s nominee to lead the Centers for Medicare and Medicaid Services on a party line vote.

Oz, a doctor and former television host ran unsuccessfully for the Senate seat in Pennsylvania now held by Democrat John Fetterman.

In his confirmation hearing, Oz said his main goals as the head of CMS deal with more transparency and eliminating waste, echoing Trump's goals.

While President Trump is claiming Laura Loomer was not involved in the NSC firings, overnight Loomer appeared to confirm that she played a role, including the latest at the NSA involving General Timothy Haugh.

"NSA Director Tim Haugh and his deputy Wendy Noble have been disloyal to President Trump. That is why they have been fired," Loomer posted on X.

She went on to thank the president for "being receptive" to vetting materials she gave him.

"Thank you President Trump for being receptive to the vetting materials provided to you and thank you for firing these Biden holdovers."

In a separate post last night, Loomer said she reported names to Trump of "disloyal people" in the NSC.
