States across the country are taking steps to tighten security at their capitol buildings following a warning by the FBI this week about potential armed protests ahead of President-elect Joe Biden’s Wednesday inauguration.

Though most have been peaceful, the destruction and chaos that took place on Jan. 6 at the nation’s Capitol have authorities worried about a repeat performance.
