Seven Democratic senators urged the U.S. Justice Department on Wednesday to block two mergers of major health insurance companies, saying that the proposed deals would mean higher premiums and lower-quality healthcare for consumers.
The department is reviewing Aetna Inc’s $33 billion plan to buy Humana Inc and Anthem Inc’s $48 billion proposal to buy Cigna Corp. If approved, the deals, both of which were announced last July, would reduce the number of national health insurance carriers from five to three.
