Remember this when a Republican takes the White House back.

Via The Hill:

Connecticut Sens. Chris Murphy and Richard Blumenthal, both Democrats, have called on President Obama to take executive action to close a “loophole” in federal gun control legislation.

The so-called “default to proceed” rule under the Brady Handgun Violence Prevention Act allows firearm dealers to sell a weapon to an individual if they have not been notified by the FBI of a buyer’s criminal background within three business days.

If the background check has not been completed within three days, the dealer has discretion to sell the firearm.
