The Senate Judiciary Committee postponed a markup for new gun control legislation for one week, delaying action on a controversial proposal to ban assault weapons.

The postponement also allows more time for bipartisan negotiations between Sens. Chuck Schumer (D-N.Y.) and Tom Coburn (R-Okla.) to reach a deal to expand background checks for all gun purchases. Those talks have stalled over Coburn’s objections to permanent record keeping of gun purchases becoming a part of background checks.

A national background check is not per se a problem; if it creates registration records, it is.  The bigger problem is that because many states are not sharing involuntary commitment records with the national background check system, this is going to be a lot of expense with little or nothing to show for it.  The gun control advocates have already admitted that they aren't bothering to prosecute people who lie on background checks; why would they bother to prosecute people who do transfers with background checks?
