POWs, families, former members of Congress criticize McCain for stymying POW/MIA investigation

Some compelling video criticizing John McCain for his handling of the POW/MIA investigation, or lack thereof. As an aside, I had no idea that McCain did a propaganda piece for the North Vietnamese while in captivity (these guys in the video allege that McCain did 32 such pieces). I looked online and confirmed that he did in fact do at least one.
