The entire D.C. National Guard has been activated by the Department of Defense to respond to the violent scene at the U.S. Capitol.

"The D.C. Guard has been mobilized to provide support to federal law enforcement in the District. Acting Secretary Miller has been in contact with congressional leadership, and Secretary McCarthy has been working with the D.C. government. The law enforcement response will be led by the Department of Justice," said chief Pentagon spokesman Jonathan Hoffman.

White House press secretary Kayleigh McEnany tweeted that Trump had directed the National Guard and other federal protective services to deploy -- but Trump has not called on protesters to leave as Vice President Mike Pence and others have.

In a joint statement from House Speaker Nancy Pelosi and Senate Minority Leader Schumer, the Democratic congressional leadership called on Trump to put an end to the chaos.

"We are calling on President Trump to demand that all protestors leave the U.S. Capitol and Capitol Grounds immediately," it said.

Trump so far has only called on his supporters to "stay peaceful" in a tweet. Meanwhile, a supporter of Trump's sat inside Pelosi's office as the breach of the building continued. A message was left for the speaker on a manila folder on her desk reading, "WE WILL NOT BACK DOWN."

Sources tell ABC News that a woman has been shot inside of the U.S. Capitol and has been seriously injured. It’s unclear what led to the shooting or if law enforcement was involved.

A source familiar with the situation said that D.C. Fire EMS are transporting a woman in critical condition to a local hospital.

Sources tell ABC News Trump is watching the storming of the Capitol protests on television at the White House, some close to President Trump beside themselves pushing him to do more to stop and condemn the violence playing out on Capitol Hill.

Many White House staffers avoided going to work Wednesday fearing events could be violent, and they did not want to be near the president who has been fuming for days.

Some sources tell ABC there is chatter among White House aides to personally resign as they can't stand by watching what is happening right now play out.

In an interview on Fox News Monday morning, Republican senatorial candidate David Perdue said that while he and his wife have "repeatedly" tested negative for coronavirus, he is still quarantining after coming into "close contact" last week with a campaign staffer who tested positive and hopes to participate in

"I’m going to participate hopefully tonight by virtually in this rally, but I’m so excited that President Trump is coming again," Perdue said, going on to paint the dire picture of the country if Democrats win.

Asked what he wants to hear the president say Monday, Perdue said: "First of all this is the last opportunity we will have to protect everything that we’ve accomplished in the last four years. The second thing is the last line of defense to stop the Democrats from perpetrating this radical socialist agenda. It’s as simple as that." 

As he did Sunday, Perdue blasted disclosure of the call between Trump and Secretary of State Brad Raffensperger and defended the president.

"To have a state-wide elected official, regardless of party, tape unknowing -- to tape without disclosing a conversation -- private conversation of the president of the United States and then leaking it to the press is disgusting," Perdue said.

When asked if he was concerned that GOP voters may be discouraged from participating in the aftermath of a general election Republicans continue to contest, Perdue said, "Well that’s what the Democrats want." Trump himself acknowledged post-election chaos may hinder turnout in the runoffs during his call with Raffensperger Saturday -- and blamed the secretary for it.
