'Girls Gone Wild' Internship War -- Temple Member Takes Blame ... Oy, Please Don't Call the Feds!!!

The Feds can officially stand down ... because a member of an L.A. synagogue has just accepted responsibility for a charity auction that somehow involved "Girls Gone Wild," a U.S. Senator, and the FBI.

To quickly recap -- the synagogue (Wilshire Boulevard Temple) recently auctioned off a summer internship position at the offices of Arkansas Senator Mark Pryor to help raise money for charity -- and GGW honcho Joe Francis won ... planning to give the position to the winner of his "Hottest Girl in America" competition.

Needless to say, Mark Pryor's office flipped out -- insisting it never sanctioned ANY intern auction -- and then reached out to the FBI to investigate the matter.

But a member of Wilshire Blvd. Temple named Chad Brownstein just sent a letter to Pryor's office, clarifying the whole SNAFU -- claiming he suggested the idea of auctioning off an internship position at Mark's office during a recent fundraising brainstorm session at the synagogue.

Chad says it quickly snowballed without his knowledge -- and the auction somehow went live on the Internet. Chad blames the whole thing on a "miscommunication."
