US Capitol secured after being stormed by pro-Trump supporters

The U.S. Capitol has been secured after pro-Trump protesters stormed the building on Wednesday.

The Capitol was locked down during an afternoon of chaos that followed after pro-Trump protesters charged the building as Congress began counting the Electoral College votes

The ensuing chaos prompted law enforcement and the National Guard to mobilize in response.

Neighboring Virginia and Maryland sent hundreds of State Troopers and National Guard members to the nation's capital as the crisis escalated.

Shortly after crowds surged around the building, Capitol police sent out an alert:

Lawmakers were given gas masks as police tried to control the situation inside the Capitol.

Shortly after 3 p.m., a shooting was reported inside the Capitol as the situation escalated. The woman later died at a local hospital.
