SOUTH LAKE TAHOE, Calif. -- Gov. Arnold Schwarzenegger is having his knee examined at a Los Angeles hospital after apparently suffering a torn meniscus in his knee.

The California governor was scheduled to attend a summit on climate change in South Lake Tahoe, but pulled out at the last minute Saturday.

California Senator Dianne Feinstein told the crowd at the summit that the governor called her early Saturday to tell her he was on his way to a Los Angeles hospital.

Schwarzenegger's spokesman, Matt David, says the governor injured his knee recently and it was bothering him all week. He says a Border Governors' Conference the governor hosted in Hollywood this week and ongoing budget negotiations in Sacramento have kept him from getting it checked out until now.

Schwarzenegger is scheduled to return to work Monday.
