Correspondence. A letter to Gordon. ~ Through a South Vietnamese student now at Harvard, Ngo Vinh Long, he's got a line on six priests from Saigon who are willing to come to the United States to speak in a national tour on the whole issue of the blood bath and the myth of reprisals against Catholics if the U.S. were to withdraw. The problems are the mechanics of the trip and its financing. He asks Gordon to help in either respect.
