The top Democrat and Republican on the Senate’s antitrust committee led a grilling of the CEOs of Kroger and Albertsons on Tuesday over their planned $25 billion grocery megamerger, which comes after months of rising inflation that has hit consumers hard. “The companies assure us that this is the merger that will make everything better,” said Sen. Mike Lee (R-Utah), ranking member of the Senate Judiciary Subcommittee on Competition Policy, Antitrust and Consumer Rights.
