From the Chronicle of Philanthropy: Three members of Congress have requested a federal investigation into news reports that the Internal Revenue Service conducts reviews of churches and other places of worship based on the content of sermons or other discourse delivered as part of religious services or gatherings. "While the federal tax code prohibits tax-exempt organizations, including churches, from intervening in political campaigns and elections, we believe the faith community has every right to express itself in the political process and be heard," said the members of the House of Representatives in a letter to the Government Accountability Office, the investigative arm of Congress.
