Mattson has been the guest of honor at State Department dinners and has met with senior Pentagon officials during the Bush administration. She also spoke at a prayer service at the Democratic National Convention in Denver. Mattson, who was elected president of the society in 2006, is a professor of Islamic studies at Hartford Seminary in Hartford, Connecticut.

But in 2007 and as recently as last July, federal prosecutors in Dallas filed court documents linking the Plainfield, Indiana-based Islamic society to Hamas, which the US considers a terrorist organization.

Neither Mattson nor her organization have been charged. But prosecutors wrote in July that they had "a wide array of testimonial and documentary evidence expressly linking" the group to Hamas and other radical groups.

Linda Douglass, a spokeswoman for Obama's inaugural committee, would not discuss the case or say whether the committee knew about it.

All this was going on while officials in the law enforcement and intelligence community apparently had evidence that the Islamic Society of North America had ties to terrorists and to the Holy Land Foundation. That foundation and five of its former leaders were convicted at a retrial in November of funneling millions of dollars to Hamas.

Appearing shocked, Winfrey responded, "Well, you are the first minister I've ever heard say, 'Being gay is a gift from God,' I can tell you that." Bacon's controversial statement sparked a fiery debate on Winfrey's website, leading the talk show host to invite the Episcopal priest back to elaborate on what he meant.

"I meant exactly what I said," Bacon, rector of All Saints Episcopal Church in Pasadena, told Winfrey via video a few days later. "It is so important for every human being to understand that he or she is a gift from God, and particularly people who are marginalized and victimized in our culture. Gay and lesbian people are clearly outcasts in many areas of our life and it's so important for them to understand that when God made them, God said you are good. That is a gift, that is a blessing, that is the original blessing with which every one of us is made by God and loved by God."

The Episcopal priest has repeatedly proclaimed a message of inclusiveness. In a controversial move last year, Bacon opened his church to perform marriage ceremonies for same-sex couples a week after the California Supreme Court had legalized homosexual marriage in May.

Labeling himself as "biblically oriented," Bacon claimed he's going down the road of Jesus, showing compassion and being inclusive, and not the road of condemnation and judgment.

Warren Throckmorton, and Assoc. Professor of Psychology and Fellow for Psychology and Public Policy in the Center for Vision and Values at Grove City College in Pennsylvania, doesn't believe Bacon's comments help in the ongoing debate over the Bible and homosexuality. "Traditional Christianity teaches that all people are valued by God as bearers of His image," he commented to The Christian Post. "However, moral questions surrounding sexual behavior are matters of great dispute among Christians. Rev. Bacon is less than helpful when he condemns those who disagree with him."
