Chick-Fil-A is feeling the heat after endorsing an anti-gay marriage group.

Less than 24 hours after gay website blogged about the chicken restaurant's sponsorship of a marriage seminar closely associated with the anti-gay marriage group Pennsylvania Family Institute, Chick-Fil-A's participation has been scrubbed off a website promoting the one-day event.

“From FamilyLife comes a new video guided event where couples have the opportunity to look at their relationship in a whole new way,” the website promoting the event says. “Weaving instruction from respected pastors and Bible teachers together with compelling stories, humorous vignettes, man-on-the-street interviews and more, The Art of Marriage will help couples apply what the Bible teaches about marriage in a powerful way. It's practical, funny and straight to the heart.”

Two Pennsylvania events to be held in February are being sponsored by one of the state's most active anti-gay marriage groups and, until Tuesday, presumably by Chick-Fil-A.

An early afternoon tweet from the Georgia-based restaurant chain raised more questions than it answered: “For those seeing reports of a CFA sponsorship w/the Penn Family Inst, we are looking into the issue and will provide a response ASAP.”
