CHICAGO (NewsNation Now) — State and local officials across the U.S. have prepared for armed protests at Capitol buildings in the days leading up to President-elect Joe Biden’s inauguration.

Earlier this week, the open carry of guns in Michigan’s Capitol was banned by a state panel. The move came roughly a week after the deadly riots at the U.S. Capitol, and it follows a plot last year to storm Michigan’s statehouse.

Michigan is among the majority of states that allow firearms at demonstrations. Six states: California, Hawaii, Illinois, Maryland, North Dakota, and North Carolina, plus the District of Columbia, don’t allow guns at protests. Some states permit local municipalities to enforce any restrictions.

So, which states allow firearms at demonstrations?
