US cities brace for inaugural demonstrations

Responding to warnings of potentially violent demonstrations, governors across the nation are calling out National Guard troops, declaring states of emergency and closing their capitols to the public ahead of President-elect Joe Biden's inauguration on Wednesday. State officials hope to avoid the type of violence that occurred on Jan. 6, when a mob of Trump supporters stormed the U.S. Capitol, leaving a Capitol Police officer and four others dead.

The FBI has warned of the potential for violence at all state capitols and has said it is tracking an extensive amount of concerning online chatter, including calls for armed protests. Governors across the country are sending thousands of National Guard troops to Washington, D.C., where the National Mall has been closed to the general public as part of an intense security effort. More than a dozen governors also have called out the Guard to protect their own state capitols and aid local law enforcement officers.
