Veterans Affairs Secretary Edward Derwinski announced says the government will review 34,000 Vietnam veterans' Agent Orange health claims that originally were denied.

Derwinski said Thursday the department expected to begin in June revising rules for deciding health effects caused by exposure to the herbicide used in Vietnam to defoliate trees and remove cover for the enemy. He said a final draft of rules should be published by October.Derwinski said the department would not appeal a ruling earlier this week in San Francisco by U.S. District Judge Thelton Henderson that voided the VA's action denying benefits to veterans who claimed their health had been damaged by exposure to 12 million gallons of Agent Orange used in Vietnam between January 1965 and April 1970. Henderson said the VA had misinterpreted a law that set standards by which the VA was to compensate Vietnam veterans.
