“The Trials of Ted Haggard” is the name of an upcoming HBO documentary in which the former evangelical pastor Ted Haggard opens up about his 2006 sex and drug scandal. He is the noted evangelical minister who was driven from his post two years ago following revelations that he used crystal meth and consorted with a male prostitute.

His life since then forms the basis of "The Trials of Ted Haggard," an HBO documentary coming Jan. 29th from Alexandra Pelosi, who captured Haggard a few years ago at the height of his career in the film "Friends of God."

Back than it was a stunning admission for the president of the National Association of Evangelicals, a formidable force among U.S. conservative Christians and a group that had the ear of the White House. Haggard, 52, was exiled from the New Life mega-church he founded and told by church elders to leave Colorado after admitting "sexual immorality" and buying methamphetamines from a male prostitute.

On January 29, a HBO documentary about Haggard will air on the cable TV network. Haggard’s wife and two of his children came on a panel for U.S. television critics to endorse his documentary, "The Trials of Ted Haggard."

Talking of the documentary, Haggard said, "I don't think it is a flattering piece. I think it is even-handed. It is embarrassing for me for people to see it, but it does answer their questions."

As for the drug allegations, Haggard portrayed himself as a neophyte. "I grew up in a sheltered and protective way, and I'm not sure what I bought. . . . I am so grateful I'm not a drug addict." Haggard also had a message for the male prostitute who exposed his secret life. "I apologized to Mike Jones," he said. "For the relationship we developed. It was a very bad mistake on my part."

And Haggard craftily dodged any specific answers to questions about his own sexuality. When journalists repeatedly tried to get Haggard to commit to being either straight or gay, the closest he came to answering the question was the cryptic statement, "I think sexuality is both confusing and complex."
