The FBI just announced that the Charleston shooter didn't pass his background check -- and should never been able to get that gun.

He was flagged by the FBI for further investigation, but because of an NRA-backed loophole in the law, the gun dealer was allowed to make the sale after three days passed -- even though the check was incomplete.

The Charleston shooter got his gun because the clock ran out on his background check, just like thousands of other dangerous people every year.

Sign the petition telling Congress to close the Charleston loophole and stop allowing gun sales without background checks now.
