Trump antitrust enforcer vows to scrutinize mergers

Makan Delrahim, who's expected to be confirmed this week as head of the Justice Department's Antitrust Division, believes some so-called vertical mergers (such as the proposed AT&T-Time Warner deal) could pose anticompetitive concerns. He also said he will "vigorously enforce antitrust laws with respect to online platforms." "Just because a transaction or particular types of transactions have been approved in the past does not mean that they could not raise competitive concerns in the future," he said in written responses to questions submitted by Senators after Delrahim's short confirmation hearing.
