My private view was that it would be naive to believe there would be any action or statement on this from the WH. For a couple of reasons: Obama has some close links to Farrakhan; Eric Holder has some close links to Farrakahn; and the Pols have been on a long term trend to "empower" religious communities through various funding mechanisms for years.
Going to Congress? Good luck with that. I think the only way to bring this to a head is via the courts. Let the Indie Scngsts start claiming tax deductions for Indie "services" (Not on a 'fixed donation schedule", but just what they have given to others for "Scn Services".) If the IRS dis-allows them, then you have a HUGE "Establishment Clause" issue, which would go I'm sure to the Supreme Court.
Unfortunately, it would cost upwards of $1 million to take it through the courts and up the ladder. It is the only route, I see though, that would impinge enough to make any kind of difference.
A brilliant "Establishment Clause" and "Equal Protection" idea to consider.
