The Justice Department won’t challenge T-Mobile US Inc.’s $4.4 billion purchase of US Cellular Corp.’s wireless operations and some of its spectrum assets, despite some concerns about the deal.

Mobile's $4.4 billion acquisition of UScellular on Thursday, the latest deal blessed by the Trump administration as it takes a softer approach to corporate consolidation than its predecessor.

The Justice Department on Thursday said its antitrust division won’t seek an injunction to prevent T-Mobile from closing on its proposed acquisition of U.S. Cellular. After the department evaluated the deal, it determined that “the potential harm and offsetting benefits of the transaction do not warrant an enforcement action.”
