US Capitol lockdown: Indiana Congress members tell Trump supporters to stand down Kaitlin Lange, Indianapolis Star Replay Video UP NEXT Republicans in Indiana's congressional delegation have used social media to tell President Donald Trump's supporters to stand down as people continued to swarm the U.S. Capitol building Wednesday, including some who had questioned the validity of the election results. Congress was debating the certification of Electoral College results Wednesday afternoon when the crowd of protesters outside breached the building, requiring the Capitol to go on lock down. For months, Trump has unsuccessfully tried to overturn results in several battleground states, claiming the election was stolen despite no evidence of widespread fraud. Some Republicans in both chambers had planned to object to the certification of electoral votes for Biden.
