LANSING (AP) — A board overseeing Michigan’s Capitol determined it has the legal authority to decide whether guns will continue to be allowed in the building and on its grounds.

The Michigan State Capitol Commission reviewed a formal legal opinion by attorney Gary P. Gordon that said the board had the power to prohibit firearms at the Capitol.

In April, a number of people carrying semi-automatic weapons and other guns took part in a protest at the Capitol over Democratic Gov. Gretchen Whitmer’s orders that closed many businesses in the state to slow the spread of the COVID-19 virus.

The “American Patriot Rally” started on the Statehouse steps, where members of the Michigan Liberty Militia stood guard with weapons and tactical gear, their faces partially covered. They later moved inside the Capitol along with several hundred protesters, who demanded to be let onto the House floor, which is prohibited.
