William Barr will have a decision to make if the Senate confirms him as President Trump’s new attorney general: whether to release special counsel Robert Mueller’s final report on his investigation into Trump’s alleged collusion with Russia.

During his confirmation hearing in the Senate Judiciary Committee, Democrats this week pressed Barr to release the full report. But Barr left them hanging on that question, and he said only that he would “provide as much transparency as I can consistent with the law.”
