John Travolta "Disappointed" About Mistrial, But Not Backing Down

Star will testify again now that Bahamian judge orders do-over in the extortion case over son Jett's death

John Travolta is hanging tough.

Hours after a Bahamian judge declared a mistrial due to possible juror misconduct in the extortion case over the death of son Jett, the star is gearing up for another shot at former Sen. Pleasant Bridgewater and ambulance driver Tarino Lightbourne, who tried to make off with a quick $25 million from the mourning Travolta and wife Kelly Preston.

The actor gave an emotional testimony last month chronicling the moments before and after he found his 16-year-old unconscious. And now, he's preparing to do it all over again.

"We are disappointed to hear about the alleged juror misconduct, since we know that the Bahamian government, the court, the other jurors and John Travolta as the victim want to have this matter adjudicated through the judicial system," Travolta's rep, Sam Mast, tells E! News. "Mr. Travolta has and will continue to cooperate with the Bahamian authorities in the prosecution of the defendants for extortion."

Travolta's lawyer, Michael Ossi, confirmed yesterday that the star is "committed to seeing justice served" and would be willing to return to the Bahamas to testify in the retrial, which has yet to be scheduled.
