Cooper mobilizes National Guard for duty in D.C., N.C.

At least 10,000 National Guard troops will be in Washington, D.C., by Saturday Some will be obvious: officers in uniforms, checkpoints, metal detectors, fencing. Some won't.

More than 6,000 members have already been mobilized to work in 12-hour shifts on Capitol grounds and work traffic control points throughout the city.

The North Carolina National Guard will be deployed for about a week. Guardsmen will provide site security, establish checkpoints and protect critical infrastructure.

North Carolina is one of dozens of states providing personnel to Washington, D.C. ahead of the inauguration of Joe Biden and following a protest that turned into a deadly riot at the U.S. Capitol last week.

Egged on by President Donald Trump and his repeated attempts to delegitimize Biden’s win, the violent mob marched from the White House to the Capitol, where they occupied the building for hours to try to stop lawmakers from certifying Biden's win. Five people died, including a police officer. Two explosive devices were found, but they did not go off.

On Wednesday, President-elect Biden was briefed by the FBI, Secret Service and key members of his national security team about the threat for additional violence leading up to his inauguration.

On Monday, the FBI warned of plans for "armed protests" in state capitals across the country.
