WASHINGTON (AP) — Brian Cole Jr. has confessed to planting a pair of pipe bombs outside the headquarters of the Republican and Democratic national parties in Washington on the eve of the U.S. Capitol attack, according to sources familiar with the investigation. Cole, who has also publicly articulated support for former President Donald Trump and the belief that the 2020 election was stolen, has provided further insights during his post-arrest cooperation with law enforcement.

Little is known about other details shared with investigators, and the FBI has not disclosed potential motives or any connections to the violent events at the Capitol the following day.

Cole faces explosive-related charges connected to the January 5, 2021, placement of the devices. Fortunately, no one was injured, as authorities were able to deactivate the bombs, which the FBI noted could have resulted in significant harm.

According to an FBI affidavit, investigators traced Cole's activities through credit card transactions linked to purchases of bomb components and location data from cellphone towers. This marks a key development in a case that has long puzzled investigators following the Capitol riots. Cole's impending court appearance is set for Friday, and his public defender has declined further comment.
