The No. 3 and No. 4 wireless providers are trying to win approval for their merger from the Justice Department and the Federal Communications Commission, but the effort may be in trouble. Top executives from T-Mobile and Sprint have been in Washington for much of the past month for meetings with the FCC and Justice Department to convince them the merger is necessary for the companies to compete effectively with Verizon and AT&T, which together control more than 70% of the wireless market.

In an interview on CNBC, Justice Department Antitrust Division chief Makan Delrahim said that the meetings were ongoing as regulators review the deal.
