The new chairman of the House Permanent Select Committee on Intelligence is committed to uncovering the truth behind a mystery that has befuddled the U.S. intelligence community since 2016.

Rep. Rick Crawford (R-AR) is an Army veteran who recently replaced Rep. Mike Turner (R-OH) as chairman of the intelligence committee. He will now lead House oversight of the intelligence community and attend the most classified congressional briefings as a member of the so-called “Gang of Eight.” That group includes the Senate and House majority and minority leaders, as well as the chairs and vice chairs of the Senate and House intelligence committees. “Gang of Eight” briefings are reserved for classified matters deemed so sensitive they cannot be briefed to the full intelligence committee.
