 New Haven Congresswoman Rosa DeLauro is blaming greedy corporations for the sky-high prices of food. DeLauro says large grocery stores exploit product shortages to jack up prices using inflation as a cover for their own greed. The 3rd District Democrat also says the wages being paid to store workers are not keeping up with the cost of food products. DeLauro spoke on the issue outside Nika's Market in East Rock, where a dozen eggs currently sell for $7.99.
