Sarah Palin appeared at a fundraiser in San Diego Saturday under extra security because of a reported death threat against her and slammed what she calls the "lamestream media."The former Alaska governor and Republican vice presidential candidate went on stage at the Sheraton San Diego Hotel and Marina on Harbor Island just after 8 p.m., where she introduced Alaska Republican Senate candidate Joe Miller, the Union-Tribune reported on its website.Standing in front of a row of American flags, Palin said the "lamestream media just doesn't get it, and when they don't believe what perhaps your message is, so they want to belittle you and mock you and treat you with much disdain, you know, I think, well they can do that to me, that's fine, because I know truth.""You know what, you can say whatever you want to say about me but I raised a combat vet and you can't take that away from me," she added.The event was organized by the political action committee Combat Veterans for Congress to publicize former combat veterans running for Congress in the Nov. 2 election.Tickets cost at least $300 a person, and about 500 people were expected to be at the event, called "Patriotic Gala."Rep. Duncan Hunter, R-Alpine, and Republican congressional candidates Nick Popaditch, who is running in the 51st District, and Michael Crimmins, who is running in the 53rd District, were among the local congressional candidates at the event.Palin told organizers she did not want to overshadow Miller, but many of the people at the fundraiser were there to see her, the newspaper reported.A death threat against her before the event caused organizers to beef up security.Combat Veterans for Congress Chairman Joseph John said the group was "very concerned about about her security."Sheraton hotel manager Warren Nocon told the newspaper the hotel had planned to have security at the fundraiser even before the threat was revealed.
