The FBI have arrested a suspect in the pipe bomb plot that has vexed investigators for nearly five years. Multiple press reports have announced the suspect as Brian Cole, Jr., from Woodbridge, Va. The pipe bombs, which were never detonated, were described as viable and possibly deadly by the FBI. Security camera footage obtained by law enforcement showed that the pipe bombs had been planted on Jan. 5, but they were not discovered until after the Capitol siege the following day.
