Meet the IRS Team in Charge of Exempt Organization Reviews
David Fish is the acting director of Exempt Organizations Rulings and Agreements at the IRS.
Fish helped implement electronic applications for exempt status. The electronic applications apparently didn't speed up the process for Tea Party groups who have been waiting years for determinations.
Melany Partner is the IRS director of Customer Education and Outreach for Exempt Organizations.
Her job is (presumably) to help applicants like the many dozens of Tea Party groups understand and navigate the IRS 501(c) application process. Obviously there's some room for improvement, to say the least.
