TCC - Was his joking statements more than a joke? was it his way of saying something happened in Roswell but we can't tell the general public?
Could it be that Obama would like to tell about the Roswell crash but can't?
Then you add in the long standing rumor that President John F. Kennedy was assassinated because he was about to tell the Truth about UFOs.
It is Clear that Kennedy had an interest in UFOs by the 2 letters/memos recently released by the CIA. You can see the letters/memos HERE & HERE .
Then you have the FBI memo that proves of a alien landing in Roswell (Can be seen HERE) and when you add it all up it makes more of a mystery as to the words of President Obama.
Interesting times we live in.
