The U.S. Conference of Catholic Bishops (USCCB) want to take birth control coverage away from all women under the Affordable Care Act, according to National Organization for Women.

According to Laura Basset, "The U.S. Conference of Catholic Bishops may be one of the quietest, yet most powerful lobbies on Capitol Hill, with political allies that have enabled them to roll back decades of law and precedent...The National Organization for Women has called for the bishops conference to lose its tax-exempt status over its lobbying activities."
