U.S. Senator Bob Casey says thousands of Pennsylvania veterans may be eligible for health care benefits and don’t know it. He was in Lehigh County Monday to promote the PACT Act. He says so far, only about 20-thousand out of 100-thousand eligible state residents have applied for its benefits. The PACT Act presumes veterans or their survivors are eligible for benefits if they develop specific disabilities after serving in locations where known exposures occurred. It applies to military members who were near burn pits in the Gulf War or after September 11th, as well as to Vietnam veterans who develop certain blood conditions.
