Richardson to announce campaign in L.A.

New Mexico Gov. Bill Richardson has been campaigning for months for the Democratic nomination for president, has appeared in the major debate and, today, makes his campaign official _ in Los Angeles.
Showing the importance of the California primary next February -- not to mention the greater chance of media attention -- Richardson is set to formally announce his candidacy at a 10 a.m. news conference at the Biltmore Hotel.
Prioi to his announcement, Richardson is doing a series of one-on-one interviews with Spanish-language stations to take advantage of his Mexican-American heritage.
