I think you're talking about discoverthenetwork; it's David Horowitz's web site.

Thanks, very interesting website, I'll bookmark it.
But this is not it -- it was an article, where he published how a number of organizations basically laundered donations, so they could pretend to have various causes, and hide their leftist founders and donors, and it was full of specifics.
Maybe someday I'll come across it again.
Would you believe, I found it!
Another article worth bookmarking and reading.
