Former U.S. Capitol Police Chief Steven Sund joins'Hannity' to sound off on bureaucratic failures leading up to riot. A January 6 defendant who was allegedly found with weapons and materials to make an explosive device just blocks from former President Barack Obama's home in Washington, D.C. last week threatened to blow up a van at a government facility and attempted to threaten a congressman, federal prosecutors said Tuesday. Taylor Taranto, 37, a Washington state resident, was wanted for allegedly participating in the Jan. 6 riot when he was taken into custody by Secret Service agents on June 29 in the Kalorama neighborhood of Washington D.C., according to court documents. The arrest came a day after he live-streamed himself on his public YouTube channel when he said he had a detonator and threatened to blow up his "self-driving" vehicle at the National Institute of Standards and Technology, which is headquartered in Gaithersburg, Maryland, prosecutors said. Taylor Taranto, 37, an accused Jan. 6 rioter, was arrested last week with weapons near former President Barack Obama's home in Washington D.C., prosecutors said.
