Welcome to America! Prince William and his wife, Catherine, arrived in Los Angeles Friday afternoon for a three-day tour. The Duke and Duchess of Cambridge landed about 15 minutes late at LAX Airport, greeted by Gov. Jerry Brown and LA mayor Antonio Villaraigosa. From the airport, they headed to Beverly Hills for a business event supporting British trade and investment. From there, they will head to a reception at the residence of the British Consulate-General in Hancock Park. On Saturday, they will attend a polo match and then the BAFTA Brits to Watch event.
