Congressman Jim Clyburn had his office looted ... we know an iPad was stolen. We're told the Congressman, who has been sharply critical of Trump, is angry that the rioters found his office, which does NOT have a nameplate ... the door is unmarked, yet the rioters somehow picked that door as opposed to hundreds of others.
High-ranking Capitol police sources say Clyburn and other members believe someone from the inside must have helped located key offices.
As we reported, the FBI is especially suspicious of the way rioters zeroed in on Speaker Nancy Pelosi's office. It's virtually impossible to find in the maze, yet the rioters were inside her office within 11 minutes.
The FBI is looking to see if some Capitol cops were involved in helping the rioters. We're told authorities are looking at cell phone data -- especially from cell phones of the hundreds of officers who were off duty -- to see if they were in the building at the time of the riot. We're told the FBI is also looking at other staff who work in the building.

As we reported, one of the reasons the FBI is so suspicious is that the building has been closed to the public since March and traversing the building and finding key offices is extremely difficult. Finding these offices so quickly has raised FBI eyebrows.
