Gov. Arnold Schwarzenegger is calling out his wife, Maria Shriver, for apparently violating a state law he signed — holding her cellphone while driving. The celebrity Web site TMZ.com posted two photographs Tuesday showing Shriver holding a phone to her ear while she’s behind the wheel. It says one was snapped Sunday and the other in July. The Web site later added a video it said was shot Tuesday in Brentwood, where the family lives. It shows Shriver holding a cellphone to her ear while driving a large SUV that appears to be a Cadillac Escalade.
