Kroger

The country's largest supermarket chain is shaking up its leadership after Rodney McMullen had led the company since 2014.

A federal judge and Washington State Superior Court judge Tuesday separately blocked the proposed $24.6 billion merger between Kroger and Boise-based Albertsons Companies, which would have been the largest grocery deal in history. Albertsons officially backed out of the deal and announced it was suing Kroger for breach of contract.

Oregon is one of eight states to join with the Federal Trade Commission in an effort to hold up the proposal.

The Federal Trade Commission and 9 states want to stop the deal that would combine the country's two largest grocery store chains. The companies say they have to merge to compete with Walmart.

The final roadblock to the payment came down Tuesday, when the Washington State Supreme Court declined to review a lower court ruling favoring Albertsons.
