In 1992, McCain sparred with Dolores Alfond, the chairwoman of the National Alliance of Families for the Return of America's Missing Servicemen and Women, at a Senate hearing. McCain's prosecutor-like questioning of Alfond — available on YouTube — left her in tears.
Four years later, at her group's Washington conference, about 25 members went to a Senate office building, hoping to meet with McCain. As they stood in the hall, McCain and an aide walked by.
Six people present have written statements describing what they saw. According to the accounts, McCain waved his hand to shoo away Jeannette Jenkins, whose cousin was last seen in South Vietnam in 1970, causing her to hit a wall.
As McCain continued walking, Jane Duke Gaylor, the mother of another missing serviceman, approached the senator. Gaylor, in a wheelchair equipped with portable oxygen, stretched her arms toward McCain.
"McCain stopped, glared at her, raised his left arm ready to strike her, composed himself and pushed the wheelchair away from him," according to Eleanor Apodaca, the sister of an Air Force captain missing since 1967.
