Story highlights Kurt Busch's ex, Patricia Driscoll, requests a no-contact order, saying he slammed her into a wall

Busch's attorney denies that; Busch testifies that Driscoll is an assassin for U.S. government

Driscoll is a defense contractor; her attorney says it's normal for her to carry a weapon but she's not an assassin

(CNN) NASCAR driver Kurt Busch, who has been accused by his ex-girlfriend Patricia Driscoll of domestic assault, testified in a court hearing Tuesday that he believes Driscoll is a trained assassin and that she once showed up wearing a gown covered in blood.

While testifying in court in Dover, Delaware, over Driscoll's request for a no-contact order, Busch said that Driscoll is an assassin for the U.S. government who would go on covert missions around the world. He also said that Driscoll had claimed a character in the movie "Zero Dark Thirty" was based on her and other women.

In his testimony, Busch said that once when he and Driscoll were in El Paso, Texas, Driscoll went out in camouflage gear, only to return later wearing an evening gown covered with blood and a trench coat.

When asked by his attorney, Rusty Hardin, why he believed Driscoll is a hired killer, Busch said, "Everybody on the outside can tell me I'm crazy, but I lived on the inside and saw it firsthand."

Driscoll and her attorney, Carolyn McNeice, did not challenge Busch's testimony while in court Tuesday. Driscoll is a defense contractor and is authorized to carry weapons.
