An Indiana pizzeria under fire for saying it would refuse to cater a gay wedding shut down on Wednesday after its owners said they received threatening messages. However, a GoFundMe page set up for Memories Pizza in Walkerton has raised more than $40,000 in just six hours. The pizzeria made national headlines this week when its owners called the business a "Christian establishment" and said the state's contentious Religious Freedom Restoration Act would allow it to refuse to make pizzas for a hypothetical gay wedding.
