States across the country are trying to protect gun ownership from the long arm of Washington by proposing bills declaring that firearms made and kept within their borders are not subject to federal restrictions.

Nine states have proposed such legislation since President Obama and fellow Democrats in the Senate began trying to tighten federal gun laws in the wake of several mass shootings that occurred within months of each other.

“There’s a lot of momentum,” Montana activist Gary Marbut told on Monday.

Marbut was behind the original Firearms Freedom Act, which says the Commerce Clause allowing Congress to regulate inter-state commerce does not apply to the in-state manufacturing, selling and ownership of firearms. Montana passed the bill in 2009.
