A federal judge on Friday halted the mass firings carried out on Thursday afternoon at the U.S. Consumer Financial Protection Bureau, saying she was deeply concerned the Trump administration had violated court orders setting conditions on dismissals.

The agency, which has returned $21 billion to consumers since its inception, could lose 1,500 of its 1,700 employees, a union warned.

President Donald Trump’s attempt to fire nearly everyone at the Consumer Financial Protection Bureau has been paused by a federal judge, who says she's “deeply concerned” about the plan.
