AUSTIN, Texas — Supreme Court nominee Harriet Miers, who once owned a .45-caliber revolver (search), is not licensed to carry a concealed handgun in Texas. State officials refused Monday to reveal whether she has ever been licensed. Miers' brother gave her the Smith & Wesson (search) handgun when he was worried about her living alone in Dallas. Judge Nathan Hecht of the Texas Supreme Court, a longtime friend of Miers', has said she kept the gun for a long time.
