The deal between Sens. Joe Manchin and Pat Toomey on the gun-controlled legislation scheduled for formal Senate debate next week could make it easier to carry concealed weapons across state lines.

The provision is part of the deal Manchin, D-W.V., and Toomey, R-Pa., reached earlier this week on background checks for gun buyers and will be among the first parts of the legislation that senators will consider.

The provision is similar to the Interstate Commerce Reform Act of 2012, which was sponsored by two Republicans — Rep. Steve Scalise, Louisiana, and Sen. Orrin Hatch, Utah. The legislation failed despite strong support from the National Rifle Association.
