Mueller Investigation Interviewing Trump

On Jan. 8, former federal prosecutor Renato Mariotti analyzed news reports that Special Counsel Robert Mueller had spoken to President Donald Trump’s legal team about interviewing him in the Russia investigation.

Darrell Issa (Calif.) will be retiring, Andy Wright recounted his personal experiences as a congressional staffer enduring the incredibly unproductive hyperpartisanship that Issa introduced to the House Oversight Committee.

Meanwhile, Steve Vladeck commented on the Foreign Intelligence Surveillance Court’s certification of a standing question to the FISA Court of Review.
