A federal judge on Friday issued a temporary pause on the Trump administration’s plans to restructure various government agencies and cut tens of thousands of federal workers because the government overhaul was not authorized by Congress.

U.S. District Judge Susan Illston put a 14-day pause on the mass layoffs, siding with a group of unions, non-profits and local governments after they filed a lawsuit on April 28.

Illston said Trump may broadly restructure federal agencies, but only in "lawful ways" with approval from Congress.

"The President has the authority to seek changes to executive branch agencies, but he must do so in lawful ways and, in the case of large-scale reorganizations, with the cooperation of the legislative branch," Illston said. "Many presidents have sought this cooperation before; many iterations of Congress have provided it."

"Nothing prevents the President from requesting this cooperation—as he did in his prior term of office," the judge continued. "Indeed, the Court holds the President likely must request Congressional cooperation to order the changes he seeks, and thus issues a temporary restraining order to pause large-scale reductions in force in the meantime."

Illston's ruling was the broadest of its kind against administration efforts to overhaul the federal government, which have been led by Elon Musk and the Department of Government Efficiency, DOGE.

Fox News Digital has reached out to the White House for comment.

In February, Trump directed agencies to work with DOGE to identify targets for mass layoffs as part of the administration's plans to restructure the government.

The president instructed agencies to eliminate duplicate roles, unnecessary management layers and non-critical jobs, as well as to automate routine tasks, close regional field offices and reduce the use of outside contractors.

The group of plaintiffs said the administration's "unlawful attempt to reorganize the federal government has thrown agencies into chaos, disrupting critical services provided across our nation."

"Each of us represents communities deeply invested in the efficiency of the federal government – laying off federal employees and reorganizing government functions haphazardly does not achieve that," the groups said in a statement.

Illston scheduled a hearing for May 22 for a potential longer preliminary injunction. She said plaintiffs are likely to suffer irreparable harm without the temporary restraining order, which she said preserves the status quo.

The judge said the plaintiffs are likely to succeed on the merits of some of their claims. They accuse Trump of exceeding his authority and say that DOGE, the Office of Management and Budget and the Office of Personnel Management exceeded their authority and violated administrative law.

"The Court here is not considering the potential loss of income of one individual employee, but the widespread termination of salaries and benefits for individuals, families, and communities," Illston wrote.

Mexico has filed a lawsuit against Google after it changed the label for the Gulf of Mexico to the Gulf of America on its maps platform to match U.S. President Donald Trump's executive order to amend the name of the body of water, Mexican President Claudia Sheinbaum announced Friday.

Sheinbaum said at a press briefing that the lawsuit had been filed against the tech giant, without providing additional details.

The lawsuit comes after Sheinbaum threatened in February to sue Google for the name change.

"We are going to wait. We are already seeing, observing what this would mean from the perspective of legal advice, but we hope that they will make a revision," Sheinbaum said at the time.

Mexico’s Foreign Relations Ministry has also previously sent letters to Google urging it not to relabel the oceanic basin as the Gulf of America.

Trump signed an order on his first day back in the White House in January to rename the northern part of the gulf to the Gulf of America. The body of water has shared borders between the United States and Mexico, and Trump’s order only carries authority within the U.S.

Mexico has argued that the Gulf of America label should only apply to the part over the U.S. continental shelf. The U.S. has control over about 46% of the gulf, Mexico controls about 49% and Cuba controls about 5%, according to Sovereign Limits, a database of international boundaries.

"What Google is doing here is changing the name of the continental shelf of Mexico and Cuba, which has nothing to do with Trump’s decree, which applied only to the U.S. continental shelf," Sheinbaum said in February.

The gulf appears in Google Maps as the Gulf of America within the U.S., as the Gulf of Mexico within Mexico and Gulf of Mexico (Gulf of America) everywhere else. It had been called the Gulf of Mexico for more than 400 years.

Google Maps began using Gulf of America for users in the U.S. shortly after Trump's order, citing its "longstanding practice" of following the U.S. government’s lead on these matters. In cases where official names vary between countries, Google’s policy says users will see their official local names.

In February, the Mexican president shared a response from Google's vice president of government affairs and public policy, Cris Turner, who said the company would not change its policy after Trump's order.

Sheinbaum’s announcement of the lawsuit comes after House Republicans passed the Gulf of America Act in a 211-206 vote, marking the first step in codifying Trump's order. The legislation now heads to the Senate.
