CNN says the US Capitol is once again secured but four people are dead -- including one woman who was shot -- after supporters of President Donald Trump breached one of the most iconic American buildings, engulfing the nation's capital in chaos after Trump urged his supporters to fight against the ceremonial counting of the electoral votes that will confirm President-elect Joe Biden's win.

Shortly after 1 p.m. ET Wednesday hundreds of pro-Trump protesters reportedly pushed through barriers set up along the perimeter of the Capitol, where they tussled with officers in full riot gear, some calling the officers "traitors" for doing their jobs.  About 90 minutes later, police said demonstrators got into the building and the doors to the House and Senate were being locked.  Shortly after, the House floor was evacuated by police.  Vice President Mike Pence was also evacuated from the chamber, he was to perform his role in the counting of electoral votes.

An armed standoff took place at the House front door as of 3 p.m. ET, and police officers had their guns drawn at someone who was trying to breach it. A Trump supporter was also pictured standing at the Senate dais earlier in the afternoon.

A woman, who is yet to be identified, died after being shot in the chest on the Capitol grounds, DC police confirmed to CNN.  DC Police Chief Robert Contee said three other people died from medical emergencies during the riot.

Politicians blame Trump for insurrection on Capitol Hill.

The riots at the US Capitol shocked many in the United States and around the world, but for some, the violent scenes in Washington are simply the natural culmination of Donald Trump’s baseless claims of voter fraud and repeated stoking of division in the United States, according to The Guardian.

Derrick Johnson, the president of the NAACP civil rights organization and others called for Trump to be impeached for his role in the siege of the Capitol.  Some Democratic members of Congress have already said they support that measure.

Reuters reports that former Republican President George W. Bush yesterday condemned the rioting at the U.S. Capitol and said he was appalled by the “reckless behavior of some political leaders since the election.”

“It is a sickening and heartbreaking sight,” Bush said in a statement.  “This is how election results are disputed in a banana republic - not our democratic republic.”

He said the violent assault on the Capitol was undertaken by “people whose passions have been inflamed by falsehoods and false hopes.  Insurrection could do grave damage to our nation and reputation.”
