From Chronicle of Philanthropy: A Catholic organization in Missouri has asked candidates for state office to return contributions from a charity that advocates for stem-cell research. The move prompted a complaint from the Internal Revenue Service that the request violates prohibitions on political activity by charities. The Missouri Catholic Conference sent the request to more than 50 candidates who received money from the group, Supporters of Health Research and Treatments. State legislators are considering an amendment to the State Constitution that would prohibit state and local governments from discouraging stem-cell research, a move the conference opposes. Lawrence A. Weber, executive director of the Missouri conference, said he was looking into the complaint. Officials from Supporters of Health Research and Treatments could not be reached for comment.
