A federal judge in Washington, D.C., on Thursday denied a request by unions to block efforts by Elon Musk’s so-called Department of Government Efficiency to drastically slash the size of the federal workforce. In his ruling, U.S. District Judge Christopher Cooper acknowledged the mass firings have already caused “disruption” and “chaos,” but said the issue should first be adjudicated by the Federal Labor Relations Authority. Earlier this month, Trump fired the FLRA’s chairwoman, Susan Tsui Grundmann, whose tenure was not set to end until July.
