U.S. capitals on edge for armed protests

As Washington, DC was locked down and transformed into a veritable fortress Saturday, state capitals around the country were bracing for the kind of mayhem Americans witnessed on January 6th.

Law enforcement officials geared up for pro-Trump marches in all 50 state capitals this weekend, erecting barriers and deploying thousands of National Guard troops to try to prevent a repeat of the violent attack at the U.S. Capitol.

The FBI warned police agencies of possible armed protests starting Saturday through President-elect Joe Biden's inauguration on Jan. 20, fueled by supporters of President Donald Trump who believe his false claims of electoral fraud.

Michigan, Virginia, Wisconsin, Pennsylvania and Washington were among states that activated their National Guards to strengthen security. Texas closed its Capitol through Inauguration Day.

Law enforcement officials have trained much of their focus on Sunday, when the anti-government "boogaloo" movement flagged plans to hold rallies in all 50 states.

The scramble followed the deadly Jan. 6 attack on the U.S. Capitol in Washington by a mix of extremists and Trump supporters, some of whom planned to kidnap members of Congress and called for the death of Vice President Mike Pence as he presided over the certification of Biden's victory in November's election.
