June, 1970 -- Kerry joins Vietnam Veterans Against the War (VVAW), a national veterans group that is part of the Peoples Coalition for Peace and Justice. The PCPJ is a broad coalition of local and national organizations, including the Communist Party, USA, "committed to conducting demonstrations aimed at ending the war in Indochina, and poverty, racism and injustice at home." The VVAW, CCI and PCPJ all have headquarters at 156 Fifth Avenue in New York City. VVAW Executive Secretary Al Hubbard, a former Black Panther, is also on the coordinating committee of the PCPJ. Hubbard soon appoints Kerry to the VVAW's Executive Committee, bypassing the normal election process.
November 22, 1970 -- During a fund-raising tour for GI deserters, Vietnam Veterans Against the War and the Black Panthers, Jane Fonda is quoted in the Detroit Free Press as telling a University of Michigan audience:
"I would think that if you understood what communism was, you would hope, you would pray on your knees that we would someday become communist," and "The peace proposal of the Viet Cong is the only honorable, just, possible way to achieve peace in Vietnam."
