Fisher, Ariza, Walton and Karl for Obama

Derek Fisher, Trevor Ariza, Luke Walton and Coby Karl are among the athletes expected to attend a fundraiser for presidential candidate Barack Obama Sunday night in Hollywood.

Other guests include: Cuttino Mobley, Al Thornton, Steve Francis and James Blake.

Fisher has been an active supporter of the Illinois Senator. In late September, before the Lakers opened training camp, Fisher stumped for Obama at two Indian reservations in Montana.

Here's an excerpt of the story in the Great Falls (Mont.) Gazette:

The Los Angeles Lakers point guard was on the reservation on behalf of the Barack Obama campaign. Fisher said he volunteered his services to campaign officials, thinking he would be dispatched to events in southern California or his hometown of Little Rock, Ark.

"I had no idea it would turn into these type of opportunities," he said, adding that he is humbled by the campaign's trust in him.
