"Sprint Corp. board members Masayoshi Son and Dan Hesse met recently with Justice Department officials who said they would view a Sprint acquisition of wireless rival T-Mobile US Inc. with skepticism, people briefed on the conversation said," the Journal reported. "The message from regulators shouldn't have come as a surprise," the newspaper noted. "In April, the Justice Department wrote in a comment letter to the FCC that the four wireless carriers competed in ways that are important to consumers. The FCC has sent similar signals."
