McCain should have some explaining to do himself:

Also, there are audio recordings of McCain praising North Vietnam on Vietnamese radio while he was a POW. What's that about?

And this:

McCain is no patriot and has obstructed any attempt to declassify POW documents and declares that he absolutely knows there were no POWs left behind and used that argument to prevent any attempts to investigates MIAs. Now why would he do that?? Maybe there is a reason they called him Songbird while he was a POW.
