Government finds out about the supernatural

[wynnebat]

I've been reading elfinblue's brilliant When Worlds Collide, where the top tier of the government is brought into the secret. Can anyone rec me something similar? Anything where the government or some official agency or even the country at large is told/finds out about the supernatural world. Pairings can be gen/het/slash/wincest, etc, and the story can be a crossover with something else. I've already read Unexpected Destinies and Jujuberry136's Criminal Minds crossovers.

Thanks!
