Fight heats up over T-Mobile's $26 billion deal with Sprint

T-Mobile CEO John Legere and Sprint executive chairman Marcelo Claure will pitch their companies' $26 billion merger before Congress, hoping to ease lawmaker's concerns about wireless competition while pushing the tie-up as a key part of the nation's 5G quest. It's a key test for a deal that would reduce the number of major national wireless carriers from four to three. The deal's opponents are fighting an uphill battle against a generally business-friendly administration, but the upcoming hearings let them air their concerns and turn up the heat.
