The AG can't bring up new legislation. He's not a member of Congress.
It was only brought up in the sense that the attorney general was talking out of turn. He was swiftly repudiated by the Speaker of the House and apparently also by the leader of the Senate, neither of whom apparently see any political benefit of taking on the gun lobby at this time.
The rumor that I get from some friends who have ties to Justice is that Rahm Emanuel also delivered a "WHAT THE EFF WERE YOU DOING!??!" message to the AG on behalf of the President.
