Shaken U.S. Capitol on high alert for Biden's first address to Congress Reuters | Apr 27, 2021 10:44 PM EDT Security fences, erected following the January 6th attack, are seen surrounding the U.S. Capitol in Washington, U.S (Photo : REUTERS/Carlos Barria) President Joe Biden's first address to a joint session of Congress on Wednesday will take place in a U.S. Capitol on high alert, with memories fresh of the deadly Jan. 6 attack on the building by supporters of his predecessor, Donald Trump. The crowd inside the Capitol will be a fraction of the hundreds of members of Congress, Supreme Court justices, top government officials and guests who typically attend, to allow for more social distancing in a COVID-19 pandemic that has killed more than 572,000 Americans.
