WASHINGTON (Reuters/AP) -- The U.S. Capitol was shut down temporarily on Monday out of an abundance of caution after a fire broke out near the complex, the Capitol Police said, underscoring security jitters days before President-elect Joe Biden’s inauguration.
"There is no threat to the public,” the U.S. Secret Service said in a tweet.
The U.S. Capitol Police said in a statement that members and staff were advised to shelter in place while the incident was being investigated.
It follows the Jan. 6 attack on the U.S. Capitol in Washington by Trump supporters, some of whom called for the death of Vice President Mike Pence as he presided over the certification of Biden’s November election victory.
All participants in the rehearsal for Biden’s inauguration were evacuated into the building, and participants were being held in the Capitol rotunda and other indoor areas, according to a Reuters witness. Biden will be sworn in on Wednesday.
The city’s fire department said on Twitter that firefighters put out an outside fire near the Capitol complex. "There were no injuries,” the department said. "This accounts for smoke that many have seen.”
FBI Vetting Guard Troops
U.S. defense officials say they are worried about an insider attack or other threat from service members involved in securing Biden’s inauguration, prompting the FBI to vet all of the 25,000 National Guard troops coming into Washington for the event.
The massive undertaking underscores fears that some of the very people assigned to protect the city over the next several days could present a threat to the incoming president and other VIPs in attendance.
Army Secretary Ryan McCarthy told The Associated Press on Sunday that officials are conscious of the potential threat, and he warned commanders to be on the lookout for any problems within their ranks as the inauguration approaches.
"We’re continually going through the process, and taking second, third looks at every one of the individuals assigned to this operation,” McCarthy said in an interview after he and other military leaders went through an exhaustive, three-hour security drill in preparation for Wednesday’s inauguration. He said Guard members are also getting training on how to identify potential insider threats.
About 25,000 members of the National Guard are streaming into Washington from across the country — at least two and a half times the number for previous inaugurals. And while the military routinely reviews service members for extremist connections, the FBI screening is in addition to any previous monitoring.
Multiple officials said the process began as the first Guard troops began deploying to D.C. more than a week ago. And they said it is slated to be complete by Wednesday. Several officials discussed military planning on condition of anonymity.
"The question is, is that all of them?
Are there others?” said McCarthy. "We need to be conscious of it and we need to put all of the mechanisms in place to thoroughly vet these men and women who would support any operations like this.”
In a situation like this one, FBI vetting would involve running peoples’ names through databases and watchlists maintained by the bureau to see if anything alarming comes up. That could include involvement in prior investigations or terrorism-related concerns, said David Gomez, a former FBI national security supervisor in Seattle.
Insider threats have been a persistent law enforcement priority in the years after the Sept. 11, 2001, attacks. But in most cases, the threats are from homegrown insurgents radicalized by Al-Qaeda, the Daesh group or similar groups. In contrast, the threats against Biden’s inauguration have been fueled by Trump’s supporters, far-right militants, white supremacists and other radical groups. Many believe Trump’s accusations that the election was stolen from him.
The insurrection at the Capitol began after Trump made incendiary remarks at the Jan. 6 rally. According to McCarthy, service members from across the military were at that rally, but it’s not clear how many were there or who may have participated in the breach at the Capitol. So far only a couple of current active-duty or National Guard members have been arrested in connection with the Capitol assault, which left five people dead. The dead included a Capitol Police officer and a woman shot by police as she climbed through a window in a door near the House chamber.
