U.S. attorney general faces daunting decision on release of Russia report

Trump fired Barr's predecessor Jeff Sessions in November after complaining for months over the decision by Sessions to recuse himself from overseeing the Russia investigation. "He has a political nightmare on his hands." Mueller, who has headed the investigation since May 2017, is due to submit to Barr his confidential report on whether Trump's campaign conspired with Russia and whether the Republican president has unlawfully sought to obstruct the probe.
