North Carolina Senator Lindsey Graham on Wednesday tweeted his support for Chick-Fil-A Appreciation Day.

Former Arkansas Governor Mike Huckabee called for people to dine at Chick-Fil-A on Wednesday in support of the fast-food chain which is facing criticism for its opposition to gay marriage.

“As a long time Chick-Fil-A fanatic, I stand with Chick-Fil-A,” Graham tweeted along with a photo of himself with a Chick-Fil-A cup in one hand. “We had it for breakfast today, but my usual order is the #1 combo with slaw and a Coke Zero. Can't beat it.” (The photo was deleted from Graham's Twitter feed, but not before it was posted at GoodAsYou.org.)

The National Organization for Marriage (NOM), the nation's most vociferous opponent of gay marriage, posted photos of crowded Chick-Fil-A eateries in Akron, Ohio, West Palm Beach, Florida, Brandon, Mississippi and Falls Church, Virginia.

“Get out there and show your support today, and make sure the Cathys know how much you honor their heroism – while at the same time making clear to the gay marriage bullies that those who believe in God's truth about marriage are strong and united,” NOM President Brian Brown wrote.
