Donald Trump announced a deal to import 300,000 metric tons of ground beef from Argentina to lower U.S. grocery prices. A "Boots on the Ground" cattle rancher warns that this move has already caused a 40-cent-per-pound drop in live cattle prices, threatening the profitability of American producers. The rancher argues that importing "scrap cuts" will de-incentivize U.S. herd rebuilding and compromise food quality.
