Chris Krebs, the former director of the Cybersecurity and Infrastructure Security Agency, resigned from his job at a private cybersecurity firm after being the target of an executive order by President Donald Trump.

Krebs, who was appointed by Trump as the first director of the new agency that Trump signed into law, resigned from his job at Sentinel One.

"As many of you know, when the news broke last week about the Executive Order -- one that directly named me and referenced SentinelOne -- I immediately reached out to Tomer. I told him what I firmly believe: this [is] my fight, not the company's, and I offered my resignation," he said in statement posted on his LinkedIn. "For those who know me, you know I don't shy away from tough fights. But I also know this is one I need to take on fully -- outside of SentinelOne. This will require my complete focus and energy. It's a fight for democracy, for freedom of speech, and for the rule of law. I'm prepared to give it everything I've got."

The executive order signed by Trump on April 9 called Krebs a "significant bad-faith actor who weaponized his Government authority." The order directed the attorney general to review Krebs' actions while director of CISA.

Krebs has long maintained that the 2020 election was safe and secure, at odds with Trump who made false claims of election fraud. Krebs' defiance of Trump ultimately led to his firing in late 2020 as CISA director.

Giving representatives of Elon Musk’s Department of Government Efficiency unlimited access to Social Security records "exposes a wide fissure in the foundation" of the agency entrusted with some of Americans’ most sensitive information, a federal judge said on Thursday.

U.S. District Judge Ellen Lipton Hollander noted that DOGE’s mission of identifying fraud is "laudable," but she said giving the group unlimited access to information – including medical records, information about children, and financial records – betrays a fundamental commitment the government has made to citizens.

"For some 90 years, SSA has been guided by the foundational principle of an expectation of privacy with respect to its records. This case exposes a wide fissure in the foundation," she wrote.

Judge Hollander specifically blocked the members of DOGE -- 11 of whom have been detailed to the SSA -- from accessing any record containing personally identifiable information, ordering that any materials already obtained that identifies individual taxpayers must be destroyed. She also blocked members of DOGE from installing any software on computer systems maintained by the SSA or altering any SSA computers.

In limited cases, she said that members of DOGE can access “discrete, particularized, and non-anonymized data” if they get written permission and explain why the information is necessary.

Last month, Hollander temporarily blocked DOGE from accessing some materials maintained by the SSA, and her order Thursday extends that order and allows the Trump administration to appeal.

Mass firings or Reduction in Force (RIF) terminations were underway Thursday afternoon at the Consumer Financial Protection Bureau, three CFPB sources told ABC News.

About 1,400 to 1,500 people from an agency that had about 1,700 employees before the Department of Government Efficiency took over are expected to be terminated, sources said. About 200 employees are expected to remain, though it's unclear what their job functions will be.

"We're still counting," one agency lawyer told ABC News after being fired.

"Well I'm now a cancer survivor who's pregnant and laid off," another CFPB employee told ABC News 15 minutes after getting their RIF notice.

In a notice to the terminated employees shared with ABC News, acting CFPB Director Russ Vought wrote that the cuts are “necessary to restructure the Bureau’s operations to better reflect the agency’s priorities and mission."

"You will be separated from Federal service effective June 16, 2025," Vought wrote. "Please be advised that you will retain access to work systems, including email and internal platforms until 6:00 PM Eastern Time, on April 18, 2025. After that time system access will be discontinued, and you will be placed in an administrative leave status through your official separation date as outlined above."

CFPB regulates and enforced student loans and was set up after the 2007-2008 financial crisis to protect consumers from unfair, deceptive, or abusive practices. The agency has a massive amount of data on corporations and businesses collected from its investigations and clawed back billions of dollars for consumers.

Trump signed a memo extending the federal hiring freeze for all federal civilian employees in the executive branch until July 15.

Enacting a federal hiring freeze was one of Trump's first actions on Inauguration Day. According to a fact sheet from the White House about the extension, the memo also clarifies that "once a merit hiring plan has been adopted, any hiring of employees exempt from the freeze shall be consistent with that plan."

The fact sheet also says that once the hiring freeze ends, agencies can hire "no more than one employee for every four employees that depart from federal service (with appropriate immigration, law enforcement, and public safety exceptions)."
