The skirmishes occurred outside in the very spot where president-elect Biden will be inaugurated in just two weeks.

Trump’s relentless effort to overturn the election results and cling to the White House drew a massive crowd to the White House, and then Trump sent them to the Capitol.

Protesters tore down metal barricades at the bottom of the Capitol’s steps and were met by officers in riot gear. Some tried to push past the officers who held shields and officers could be seen firing pepper spray into the crowd to keep them back. Some in the crowd were shouting “traitors” as officers tried to keep them back.

A suspicious package was also reported in the area, Capitol Police said.
