"Of course its not illegal."
It is illegal for a tax exempt religious institution to endorse a political candidate. Reverend Wright viciously vilified Barack Obama's competitor, Hillary Clinton and her husband, and praised Barack Obama to his congregation, after Barack Obama donated $22,000.00 to this church last year. I heard the church will be investigated for this violation of federal law, and their tax exempt status may be threatened.
I question whether there was a quid pro quo involved in this transaction between Obama and the Reverend Wright.
