Trump admin updates: Trump plans to issue executive order to require voter ID

As of Sunday night, National Guard troops operating in Washington, D.C., are now armed, according to a defense official.

This will apply to the more than 2,200 guardsmen from D.C. and other states that are now serving in the mission in D.C.

Separately, a spokesperson for Joint Task Force-DC confirmed under what rules they can be used.

“The Secretary of Defense has directed JTF-DC service members to carry their assigned service weapon. Task force personnel operate under the established Rules for the Use of Force, which allow the use of force only as a last resort and solely in response to an imminent threat of death or serious bodily harm. JTF-DC remains committed to protecting the safety and wellbeing of the residents of the District of Columbia,” a JTF-DC spokesperson said in a statement.

“Soldiers will be able to carry their service-issued weapons, which may include M-17 pistols or M-4 rifles,” the statement continued.

A U.S. official confirmed to ABC News that planning is underway at the Pentagon for the potential use of National Guard forces in Chicago.

The possible call-up of National Guard members in that city was first reported by the Washington Post.

The Pentagon did not provide a comment, but a Defense official said, “We won’t speculate on further operations. The Department is a planning organization and is continuously working with other agency partners on plans to protect federal assets and personnel.”

Appearing on CNN’s “State of the Union” on Sunday, House Minority Leader Hakeem Jeffries, D-N.Y., said, “There’s no basis, no authority for Donald Trump to potentially try to drop federal troops into the city of Chicago.”
