[img_assist|nid=1274|title=U.S. Sen. John McCain|desc=Getty Images Photo|link=none|url=undefined|align=right|width=200|height=300]U.S Sen. John McCain (R-Ariz.) has added a Tuesday morning appearance in Santa Barbara to his California swing, with his campaign Web site saying the presumptive Republican presidential nominee will have an environmental briefing.

The appearance will be at the Santa Barbara Museum of Natural History, with doors opening at 7:30 a.m. The event is open to the public and McCain is scheduled to speak at about 9 a.m.

Monty Ward, chair of the Santa Barbara County Republican Party, said he's unsure of what McCain plans to say at his appearance, but noted it could be a follow-up to his push last week for more offshore oil drilling, including in California.

A handful of oil derricks operate off the coast near Santa Barbara, but a spill there in the late 1960s hardened state residents' opposition to widespread drilling off the California coast.

California Gov. Arnold Schwarzenegger, a McCain ally, is on record as opposing any offshore drilling expansion in California.

McCain spoke at a town hall meeting in Fresno Monday morning, and according to press accounts took questions on such topics as the war in Iraq, gas prices, illegal immigration and his presumed rival for the presidency, U.S. Sen. Barack Obama (D-Ill.).About 600 people attended that event.

McCain was also attending a private fundraiser in Fresno after the town hall meeting. McCain's campaign staff would not disclose how many people attended the fundraiser or how much it raised.

The Arizona senator is scheduled to attend another fundraiser in Riverside on Tuesday afternoon.
