Some 200000 flags now cover part of the National Mall and will represent those unable to travel to Washington, DC, for Wednesday’s inauguration of President-elect Joe Biden. The display was organised by the Presidential Inaugural Committee. Echoing the “America United” theme chosen for inauguration week, the display features 191,500 U.S. flags and 56 pillars of light, the latter chosen to symbolise every U.S. state and territory, according to the Presidential Inaugural Committee.
