    Gee Mom, look what else I've found!




"Many years ago when I was imprisoned in North Vietnam, there was an attempt to rescue the POWs, unfortunately, the prison had been evacuated. But the brave men who took on that mission and risked their lives in an effort to rescue us prisoners of war were genuine American heroes. Because the mission failed did not in any way diminish their courage and willingness to help their fellow Americans who were held captive. Mr. Spicer should know that story." - John McCain
