Republicans on the House Intelligence Committee boycotted a hearing on Wednesday, complaining that the committee's Democratic chairman Adam Schiff has neglected proper oversight of the intelligence community by failing to hold a hearing on the Justice Department inspector general’s report detailing the FBI's FISA abuses.“Under your chairmanship, the House Intelligence Committee has strayed far from its mandate of overseeing the Intelligence Community,” the panel's nine GOP members wrote in a letter to Schiff obtained by the Daily Caller.“Until the Committee prioritizes oversight activities related to urgent and critical concerns, Republican Members cannot support distractions from our core responsibilities,” they added.
