The campaign, “Support Jack Phillips” on the crowdfunding website Continue to Give, began after the Colorado Court of Appeals ruled Thursday against Mr. Phillips‘ challenge of a state civil rights commission order, which said he must provide wedding cakes for same-sex ceremonies if he does so for traditional ones.

The crowdfunding page’s goal is $200,000, and, as of late Sunday, the campaign had raised about $2,000.

Mr. Phillips has said revenue at his bakery dropped about 40 percent after he stopped making wedding cakes entirely while his case is litigated.
