National Guard troops in Washington, D.C., have begun carrying firearms as former President Trump threatens to deploy troops to Chicago and Baltimore.

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.”

Trump has already deployed National Guard troops to Washington, D.C., and is openly discussing sending troops to other cities.
