Ah, we have the harbringer of doom, the naysayer of American Servicemen and Women around the world (including her son since she calls Service men and women War Mongers), apparently has a disagreement with Senator John McCain:

Sheehan said Tuesday that McCain told her then that her son's death was "like his buddies in Vietnam" and that he feared their deaths were "for nothing." McCain, however, denied he made such a statement.

Well, someone is lying.  But who?  A deranged woman or a politician?  You make the call.
