Sen. Elizabeth Warren accused three major grocery store chains of exploiting the coronavirus pandemic to exponentially raise prices for American consumers, even as the companies rake in record profits.

Warren, a former Democratic presidential candidate, suggested in separate letters to the chief executives at Publix, Kroger and Albertsons that the companies had used their massive profits earned in 2020 to reward executives with bonuses and make additional stock buybacks, all while jacking up the price of food.

“Your company, and the other major grocers who reaped the benefits of a turbulent 2020, appear to be passing costs on to consumers to preserve your pandemic gains, and even taking advantage of inflation to add greater burdens,” Warren wrote.

Americans are grappling with the hottest inflation in nearly four decades, with consumer prices in November soaring 6.8% from the year-ago period. Prices for food were no exception: In November, they jumped 0.5% from the previous month and 6.8% from the previous year.

The increases were most pronounced for different meats, with staggering year-over-year increases for beef and veal (20.9%), bacon (21%), pork chops (12.7%), fish (8%) and chicken (9.2%). Egg prices climbed 8% compared to last year, while coffee was up 7.5% and cereal was up 5.7%.

“Your companies had a choice: they could have retained lower prices for consumers and properly protected and compensated their workers, or granted massive payouts to top executives and investors,” Warren wrote. “It is disappointing that you chose not to put your customers and workers first.”

Kroger, for instance, recorded a profit of $2.6 billion in 2020, a 5.6% increase from the previous year. Albertsons reported $1.89 billion in net income for 2020, an increase from $612.1 million, and Publix reported a 60% growth in profit for the third quarter of 2020, Warren wrote.

“In 2021, these same companies continued to earn massive profits while pushing grocery cost increases onto consumers,” the progressive lawmaker wrote, pointing to a recent call with investors in which Kroger CEO Rodney McMullen said that “a little bit of inflation is always good in our business.”

Kroger, Publix and Albertsons did not immediately respond to a FOX Business request for comment.
