Recently the White House claimed there is no evidence to suggest that aliens exist, in 2011 of this month
Well the formidable and legendary Stanton Friedman PhD in Nuclear Physics (just shows credible intelligent people are aware of this phenomenon) had a little something to say about it.
Stanton is notable in this realm of investigation.
''Friedman has been criticized both by skeptics and other Roswell researchers for taking the position that there are no substantive grounds for dismissing the authenticity of some Majestic 12 documents. Friedman himself was the first to provide evidence that some of the documents are clearly hoaxes. For example, he showed that a supposed memo from Admiral Hillenkoetter to President Truman, dated February 17, 1948, was actually the emulation of a letter from Marshall to Roosevelt that featured in the book The American MAGIC. Friedman has researched the MJ-12 documents since first becoming aware of them from Wiliam Moore and Jaime Shandera in 1984. He addressed criticisms of the original documents in both sources.''
