Affected agencies include the departments of Homeland Security, Education, Energy and Health and Human Services, among others, according to a Justice Department filing.

The Trump administration on Friday began laying off more than 4,000 federal workers, according to a court filing, as the government remains shut down due to the inability of Congress to reach a funding deal.

Reduction-in-force notices are being sent to federal workers across seven departments, with the Treasury Department and Department of Health and Human Services being the hardest hit and accounting for more than half of the total layoffs, according to a new Justice Department filing.

The court filing is in response to a lawsuit over the shutdown layoffs from the American Federation of Government Employees and the AFL-CIO.
