National Guard troops from the Washington, D.C., and Virginia National Guards have been ordered to the U.S. Capitol.

DoD officials voiced concern that the public misidentified law enforcement and federal agents wearing the Army's OCP.

Leaders with 2nd Law Enforcement Battalion retired the battalion's colors last week during a ceremony at Camp Lejeune.

The senior leadership authorized the Guard to use helicopters to "observe and report" on demonstrations, officials have said.

The training has raised concerns among press organizations and free speech advocates.

The Pentagon has yet to release the findings of an investigation.

Lawmakers held the hearing to ask questions about the events surrounding the June 1 clearing operation at Lafayette Square.

A D.C. National Guard major is set to testify that a U.S. Park Police operation against peaceful protesters was "unprovoked."

The personnel are Department of Homeland Security agents dispatched to Portland after weeks of protests.

The National Guard will stress de-escalation in confronting civil unrest.
