Photos: National Guard troops deployed on Capitol Hill
Security was exceptionally tight at the Capitol on Wednesday, with shocking images of massed National Guard troops, secure perimeters around the complex and metal-detector screenings required for lawmakers entering the House chamber.
More than 20,000 National Guard members could be in the nation's capital to help secure President-elect Joe Biden's inauguration, Washington, D.C., Police Chief Robert Contee said Wednesday.
There are already significantly more U.S. troops deployed on Capitol Hill than in Afghanistan and Iraq combined, a staggering statistic that underscores just how massive the security presence is.
