OAK BROOK, Ill. —  A Christian group that opposes same-sex marriage launched a boycott of McDonald's because of the fast-food chain's support for the National Gay and Lesbian Chamber of Commerce.

American Family Association president Tim Wildmon says almost 200,000 people have signed an online pledge to boycott McDonald's for promoting homosexuality instead of remaining neutral.

McDonald's spokesman Bill Whitman says the company has made a financial contribution to the National Gay and Lesbian Chamber of Commerce, and a McDonald's executive serves on the chamber's board. He insists that doesn't mean that McDonald's supports "a particular lifestyle or same-sex marriage."
