Yesterday, Sen. Mike Lee (R-UT) sent a letter to the Department of Justice and Federal Communications Commission highlighting testimony presented at the June 27, 2018, hearing on the proposed T-Mobile US and Sprint merger. The letter draws the agencies’ attention to important issues raised by witnesses appearing at the hearing, including the resulting increase in market concentration in the wireless telecommunications industry, and the potential for the merger to create a more competitive wireless carrier. In particular, the letter addresses the potential for significant efficiencies that would benefit consumers.
