The Supreme Court was asked to rule on the legality of President Trump's appointment of acting Attorney General Matthew Whitaker.
The motion filed Friday was similar to the one filed in a Maryland court Monday. Both claim Deputy Attorney General Rod Rosenstein should've succeeded former Attorney General Jeff Sessions.
President Trump picked Whitaker to oversee the DOJ after Sessions was asked to resign. The move sparked concerns about special counsel Robert Mueller's Russia investigation, as both Trump and Whitaker have expressed disapproval of the probe. Sessions had recused himself from overseeing the investigation, so Rosenstein was in charge of it.
The Justice Department defended the president's appointment in a memo released Wednesday.
