AFA President Tim Wildmon said McDonald's had refused to end its involvement with the National Gay and Lesbian Chamber of Commerce, The Washington Post reported. McDonald's joined the chamber several months ago and has a representative on the board of directors.

"We're saying that there are people who support AFA who don't appreciate their dollars from the hamburgers they bought being put into an organization that's going to fight against the values they believe in," Wildmon said.

The AFA has boycotted a number of other companies, including the Walt Disney Co. for "its embrace of the homosexual lifestyle" and Target Brands Inc. for referring to "holiday" in ads instead of Christmas. The group recently ended a boycott of Ford Motor Co. after the automaker dropped most of its ads in gay publications.
