A federal district court judge in California said she will likely extend a freeze on President Donald Trump’s plan to lay off thousands of federal workers, dealing another blow to his unprecedented overhaul of the federal workforce.

A federal judge has extended her freeze on President Donald Trump’s plan for mass layoffs and reorganizations at 22 federal agencies until a lawsuit against his administration is resolved, saying the president “likely must” seek approval from Congress before carrying out such widespread changes.

A federal judge on Thursday continued to block the Trump administration from moving forward with its plans to lay off thousands of government workers at more than 20 federal agencies, providing federal employees a lifeline as a legal challenge to President Trump's bid to restructure the federal government moves forward.
