Barr Still Controls Whether Mueller Can Testify

Associated Press: “While Mueller is a Justice Department employee, the department would generally handle requests for him to appear before Congress, and the Justice Department could delay or block Mueller from voluntarily appearing. Congress could issue a subpoena to compel him to appear before the committee. It isn’t clear what grounds the Justice Department would use to justify an attempt to block Mueller’s testimony.”

“As a private citizen, Mueller could decide whether to accept an invitation to appear or, if he declines, whether to attempt to resist any effort to subpoena him.”
