In October, Klobuchar led letter to Federal Communications Commission and Department of Justice urging them to investigate the impact of a potential T-Mobile and Sprint merger 

WASHINGTON – U.S. Senator Amy Klobuchar, the Ranking Member of the Senate Judiciary Subcommittee on Antitrust, Competition Policy and Consumer Rights, released the following statement on the announcement that Sprint and T-Mobile plan to merge.

"This merger by T-Mobile and Sprint raises serious antitrust issues, and is exactly why I urged the FCC and DOJ to investigate a potential merger last year. Competition among the four largest cell phone carriers has led to lower prices, better service and more innovation. I remain concerned that increased consolidation could undermine benefits to consumers."
