The new ad features John Kerry in the 1970s renouncing the medals he won during the Vietnam War.

The Swift Boat group is spending $400,000 to air this ad in Florida.

The group also is spending another $800,000 on nationwide cable TV featuring their previous ad that had former POWs accusing Kerry of betraying the United States.

Here are the details of the Swift Boat Veterans for Truth's 30-second ad:

Then a scraggly, bearded, long-haired young man is shown raising his arm in a clenched-fist gesture and angrily hurling medals behind him.

Scenes of Kerry in an interview and testifying before Congress.

Announcer: "Symbols. They represent the best things about America. Freedom, valor, sacrifice. Symbols, like the heroes they represent, are meant to be respected. But some didn’t share that respect and turned their backs on their brothers.”

Kerry Speaking: "... and renounce the symbols which this country gives ... and that was the medals themselves. ... I gave back, I can’t remember ... six, seven, eight, nine."

Announcer: "How can the man who renounced his country’s symbols now be trusted?"
