Patrol officers noticed the Dodge Dakota van around midnight on Sunday. Police say the truck had no license plate, but an image of an American flag.
Officers stopped the truck and noticed a bayonet and a machete, which are illegal in the District of Columbia. The driver, identified as Donald Craighead, 44, of Oceanside, California, was arrested.
Capitol police have formally asked the Capitol Police Board to put back temporary fencing around the complex before the rally, a source familiar with the planning told CNN. The Capitol Police Board will make the final call, but the recommendation will weigh heavily in its final decision.
House Speaker Nancy Pelosi has invited Senate Majority Leader Chuck Schumer, Senate Minority Leader Mitch McConnell and House Minority Leader Kevin McCarthy to a briefing in his office with U.S. Capitol Police Chief Tom Manger to discuss security preparations for the rally, according to a family source. Leading Democratic and Republican lawmakers on the House Administration Committee are also expected to receive separate security briefings in the coming days, another source said.
