I'll keep an eye out for anything to substantiate it. It may be a link developed after the My Lai series, which was published in 1969. Hersh later followed the Winter Soldier hearings. He quotes them in the notes to his 1972 book on My Lai Cover-Up, where he says on page 273:

For information on the allegations regarding prisoner abuses, contact the Vietnam Veterans Against the War (VVAW), 25 West 26th Street, New York, N.Y., 10010. . .The testimony of its "Winter Soldier" hearings, held in January, 1971, in Detroit, Michigan, received scant newspaper attention at the time. . .A series of similar hearings has been sponsored by the Citizens Commission of Inquiry (CCI). . .another veterans' anti-war group which was organized in November, 1969, following the first public disclosures of the My Lai 4 massacre. . ."
