Concerns were also raised that Walmart executives in the United States had "hushed up" the allegations. A follow-up investigation by The New York Times, published December 17, 2012, revealed evidence that regulatory permission for siting, construction, and operation of nineteen stores had been obtained through bribery. There was evidence that a bribe of US$52,000 was paid to change a zoning map, which enabled the opening of a Walmart store a mile from a historical site in San Juan Teotihuacán in 2004.[208] After the initial article was released, Walmart released a statement denying the allegations and describing its anti-corruption policy.
