The FBI has sent a memo to law enforcement agencies across the country warning of possible armed protests at all 50 state Capitols starting Jan. 16, and also says an armed group has threatened to travel to Washington, D.C., the same day and stage an uprising if Congress removes President Donald Trump from office, according to a senior law enforcement official.
The memo includes information provided by the ATF, DEA, Defense Department, Park Police, and the U.S. Marshals, among other agencies, according to the official. Some of the information came from social media, some from open source, and some from other sources of information.
