I posted this before years ago, but just so people know, the US CONgress addressed chemtrail and HAARP back in 2001. Naturally the bill failed. But it's on the record.
Go to this link and click "Bill PDF". You'll be given the option to go to the Government Printing Office's web site. Click "Continue to GPO Site". Then read all the things that bill addresses like space based & biological weapons. And on page 5 you will see them talking about chemtrails under (III).
Here's the original link to the Library of CONgress where it all starts. You can see the chemtrails reference under
"SEC. 7. DEFINITIONS. (B) (ii),"
