Ironically, President George W. Bush, is a member of the United Methodist Church and attends the Episcopal Church. Even so, he was famously denounced in January 2003 by ECUSA Presiding Bishop Frank Griswold from the pulpit of the National Cathedral.

Reading this article makes my blood boil. If I were still holding out in one of these horrible churches, this article would probably be the straw that broke the camel's back.
