The Trump appointee making Silicon Valley sweat

One of President Donald Trump’s top regulators is raising the temperature on Silicon Valley.

Makan Delrahim, who heads the Justice Department’s antitrust division, has spent months laying out a case for greater scrutiny of the country’s powerful technology industry, making the argument in speeches from Chicago to Rome.

He faces an early test Tuesday when a federal judge rules on his first big action, a lawsuit to block the $85 billion merger between AT&T and Time Warner. The Trump administration’s argument, that the deal could stifle competition and raise prices for consumers, is a departure from the traditional GOP hands-off approach to business — and Delrahim is making it clear that the tech industry’s practices are under his microscope as well.
