Actor Gary Sinise, Fox News anchor Bret Baier and Coors Chairman Peter Coors have each decided against speaking at an upcoming conference organized by a Catholic group which believes gay people can – and should – alter their sexuality.

Legatus' 2015 Summit takes place January 29-31 at the Ritz-Carlton in Naples, Florida.

“When I accepted the invitation to speak at the Legatus conference about Veterans issues and share my story, I was unaware of the controversy surrounding some of the participants, and their views on personal matters,” Sinise said in a statement.

“I don't want my mission – which is designed to be unifying – to be disrupted by these, or any controversies, and therefore have decided to withdraw.”

Sinise's about face came after GoodAsYou.org pointed out that Legatus describes homosexuality on its website as “a selfish act that cannot fulfill the divinely ordained purpose of the reproductive powers” and encourages gay people to live a “chaste and celibate life.”

In a 2011 article, the group's John Haas wrote that people suffering from “same sex attraction disorder” can be cured.

“[T]here is hope for those who suffer from the disorder,” he wrote. “The National Association for Research and Therapy of Homosexuality reports that significant numbers of homosexual persons have undergone treatment and had their sexual drives properly ordered.”

A Fox News spokesperson told RawStory.com that Baier had also decided to withdraw from the event.

“Bret Baier has withdrawn his participation as a speaker at the upcoming Legatus Summit due to the controversy surrounding some editorial stances in the organization’s magazine,” the spokesperson said in a statement. “Bret accepted the invitation to speak about his book, his faith, and his son's congenital heart disease. He was unaware of these articles or the controversy surrounding them.”

On Wednesday, the Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, confirmed that Coors had also withdrawn from participating in the event.

Other speakers scheduled to attend include Cardinal Timothy Dolan, archbishop of New York, and Louisiana Governor Bobby Jindal.
