According to WSJ, the Trump government pressed Walmart, Kroger and Albertsons to reduce the price of beef. Wal Mart then announced that it would reduce the price of thousands of commodities, among which the price of ground beef would be reduced by up to 12%. Trump issued a document saying that Wal Mart should cut prices as required by the government, and called on other retailers to follow up. The price of ground beef in the United States increased by 12% year-on-year in May.
