Did you apply at http://www.greatagain.gov to head up an agency? It doesn't matter if you're not a Republican as a certain number of slots must be held by people outside the President's party. Heck, apply for a slot at the FCC. Be advised that as I hold a career slot I'm stuck where I am for the moment.

As to grabbing the 990, it can sometimes be dislodged by sending a Form 4506-A to the IRS who can turn over a "Modernized e-File" print: https://www.irs.gov/uac/about-form-4506a
