According to the author of this article,it was sent by Obama to congress.
And nobody in Congress made this letter public?
I only ask because I've read about this "80,000 Muslims immigrants" letter on a few sites and none have provided a link to the actual letter, only the claim that it said this. I'd like to read this letter for myself as WND has been known to "improvise" the truth just a wee bit in order to fit their narrative.
