A Catholic charity in Tucson, Arizona said Thursday that it would not accept a gift of $2,000 from mega-retailer Walmart, calling the offer “blood money.”

“We feel that even though Walmart has low prices, they pay lousy wages, they’re anti-union and they have a detrimental effect on the survival of small businesses,” Brian Flagg, who runs the Casa Maria Free Kitchen in Tucson, told The Arizona Daily Star. “We consider that blood money.”
