New York, NY —

A Vietnamese delegation is trying to sue American companies for health problems they claim are related to Agent Orange.

REPORTER: A federal Appeals court in New York heard arguments from the group yesterday. Two years ago, a federal judge rejected the case outright, but the plaintiffs want to persuade the appeals panel to give them their day in court.

REPORTER: The group argues that Agent Orange caused long-term health problems and genetic defects and that the statute of limitations has not expired.
