Campaign spokeswoman Stephanie Cutter said yesterday Mr. Kerry should not be associated in the public mind with Miss Fonda and her later trip to Hanoi, where she was photographed sitting astride a North Vietnamese antiaircraft gun. "John Kerry and Jane Fonda were just acquaintances," Ms. Cutter said. "What's important to understand here is two things: He met her before she went to Vietnam, and he did not approve of her very controversial trip." She said Mr. Kerry took part in the antiwar movement in order to bring U.S. troops home quickly.
