"In 2009, while attorney general, Brown filed a friend-of-the-court brief siding with the National Rifle Assn.'s attempt to overturn a gun ban in Chicago. Brown wrote to the U.S. Supreme Court that he feared "California citizens could be deprived of the constitutional right to possess handguns in their homes.""
