A federal appeals court panel said Trump could fire Office of Special Counsel head Hampton Dellinger for now while litigation continued, but Dellinger said Wednesday that he’s ending his legal fight.

The former watchdog for federal workers said Thursday that he intends to drop his bid for the courts to reinstate him after the Trump administration fired him without cause last month, signaling the end to the most prominent fight so far about Trump’s effort to reshape the executive branch.

An agency head fired by President Donald Trump is ending the legal battle to regain his job, admitting he is unlikely to succeed at the Supreme Court.
