MIAMI -- The girlfriend of a man charged in Miami with making threats against Democratic presidential candidate Barack Obama says he's the victim of a mistake.

Susanne Kynast tells The Associated Press that 22-year-old Raymond Hunter Geisel might have been joking about the possibility of al-Qaida leader Osama bin Laden becoming president. Kynast says he had no ill will toward Obama.

Geisel is being held without bail on charges of threatening to assassinate Obama. Kynast says Geisel never talked seriously about hurting anyone.

Authorities found weapons and other military gear in Geisel's vehicle and hotel room before his arrest last weekend. Kynast says some items were for a bail bondsman training class he was taking.
