From CQ Politics:
_With solid bipartisan support, a Senate panel approved legislation on Thursday to allow loaded guns in national parks.
The Energy and Natural Resources Committee approved, 18-5, a draft bill by Sen. Jim DeMint, R-S.C. It would allow people to bring loaded guns into national parks and wildlife refuges unless state laws bar them from doing so. Park Service regulations now allow guns only if they are unloaded and stowed.
“The purpose of this bill is to protect innocent Americans from violent crime in national parks,” DeMint said._
