President Trump’s appointment of Matthew Whitaker as acting Attorney General has prompted a “constitutional crisis,” says Tom Goldstein, the veteran U.S. Supreme Court lawyer and publisher of SCOTUSblog, who is challenging Whitaker's appointment at the high court in an unusual motion. Bloomberg Law reporters Kimberly Robinson and Jordan Rubin speak to Goldstein and Steve Vladeck, the constitutional scholar at the University of Texas who argues the temporary appointment was legal. They discuss Goldstein’s motion, other pending challenges percolating in the courts, and the effect of Trump's Dec. 7 nomination of William Barr to take over Whitaker's role full-time. Goldstein maintains that, even if Barr is confirmed by the Senate, Whitaker's appointment will still have had disastrous consequences, including for law enforcement and national security.
