The O'Keefe Media Group went undercover at CattleCon in Nashville, Tennessee, and exposed how Tyson, JBS, Cargill and National Beef secretly control America's beef market.

In November, President Trump said cattle prices were falling while beef prices kept rising and launched an investigation into price manipulation.

Trump directed the DOJ to investigate the meat packing companies who are driving up the prices through illicit collusion, price fixing and price manipulation.

The O'Keefe Media Group went undercover at CattleCon and ranchers spilled the beans on how the "Big Four" control the beef industry.

"Our team spoke directly with ranchers and industry partners, documenting firsthand how the "Big Four" dominate the market and impact pricing," James O'Keefe said.

"Tyson, JBS, Cargill, and National Beef control most of the U.S. beef industry, raising serious questions about who really sets the price. So when you see higher prices at the grocery store, it's worth asking why," O'Keefe said.

"This may explain why your steak keeps costing more," he said.

"They [Big Four] are buying like all the companies in the United States… so they don't have competition," one insider said.

"They [Big Four] can knock you out of this industry in two seconds," another said.

"They [Big Four] closed all the markets — all the markets are theirs in Brazil and now in the U.S."
