On July 31, Schwarzenegger signed a $78.8 billion budget, which was a $32 billion reduction over five years. On August 16, Schwarzenegger said he was considering giving weightlifting equipment back to prisoners, who had been barred from using weights since 1997. Schwarzenegger gave a speech at the Republican National Convention on August 31 at Madison Square Garden and closed by saying, "George W. Bush has worked hard to protect and preserve the American dream for all of us. And that's why I say, send him back to Washington for four more years." On September 13, Schwarzenegger signed the .50 Caliber BMG Regulation Act, which banned the manufacturing, sale, distribution, and importation of .50 BMG rifles, making California the first U.S. state to do so. Schwarzenegger vetoed a bill on September 22 that would have given as many as two million illegal immigrants California driver's licenses, saying the measure failed to provide sufficient security provisions at a time of heightened terrorism fears.
