Obama tries to destroy evidence linking him to Ayers

But once again Obama is caught in the Web.

Here is what Obama was trying to destroy.

"When I first met Barack Obama, he was giving a standard, innocuous little talk in the livingroom of those two legends-in-their-own-minds, Bill Ayers and Bernardine Dohrn. They were launching him–introducing him to the Hyde Park community as the best thing since sliced bread."

So, if Ayers isn't relevant to this campaign, why is Obama trying to erase records and lie about his alliance with Ayers?
