U.S. veteran Steve House, who first raised suspicions of the burial of defoliants in South Korean soil in May, said he would do his best to uncover the truth about the Agent Orange cover up at Camp Carroll.

House said in his speech at the National Assembly on Monday for victims of defoliant exposure that the U.S.’ announcement over the issue is untrustworthy and that he would do his best to aid the on-going investigation so that answers are revealed.

House said Koreans as well as past and current U.S. soldiers serving in Korea deserve to know the truth about the matter. He said he would visit Camp Carroll soon to point out the burial sites that he can recall.

Although the U.S. military has admitted to the burial of Agent Orange at Camp Carroll and has stated that it has removed the waste, House stated that if the military continues to fail to come up with documents relating to the storage and the burial of the Agent Orange drums in South Korea, then he intends to press the U.S. Congress to conduct an independent investigation on the matter. So far, a joint on-site probe by the U.S. military and South Korean officials has failed to produce any evidence of metal drums at Camp Carroll.

House also pointed out that he is currently beset with multiple diseases, including peripheral nerve disorder, glaucoma, and skin rashes. He said he believes that the diseases he currently has are linked to the exposure to harmful chemicals while serving in South Korea.

House and his group arrived in Korea via the Incheon International Airport on Sunday. They will visit Camp Carroll on Wednesday before departing the nation on Friday.
