Telecon with GAP -Witness A (alsoA-5):
1/23/85 (1000 EST)
I called GAP alleger "A" in order to arrange for a feedback interview of a few remaining items yet to be covered. Alleger informed me would not be' able.to meet with TRT at this time, so I suggested a letter outlining the resolution of these few remaining items. A11eger agreed that'this would be an acceptable method for completing ~these issues.
