Per the Hill, the Republican Senate is taking up concealed carry reciprocity:
Gun owners would be allowed to carry concealed weapons around the country under new legislation in the Senate.
The Senate’s No. 2 Republican, John Cornyn, will reintroduce a gun rights bill Thursday that critics warn is dangerous.
The Constitutional Concealed Carry Reciprocity Act would allow gun owners who have a concealed carry permit in their home state to bring their firearms in any other state with concealed carry laws.
“This operates more or less like a driver’s license,” Cornyn told The Hill. “So, for example, if you have a driver’s license in Texas, you can drive in New York, in Utah and other places, subject to the laws of those states.”
Cornyn, a Texas Republican, said this would “eliminate some of the ‘gotcha moments,’ where people inadvertently cross state lines” with guns they are legally allowed to carry in their home state.
