Alphabet’s Google may soon have more federal regulators breathing down its neck.

President Trump’s antitrust chief at the Department of Justice told Capitol Hill lawmakers on Wednesday that his agency could investigate the search giant for anti-competitive behavior.

The Federal Trade Commission closed a 20-month antitrust probe of Google’s search practices in 2013without taking any action.

At the time, those close to the regulator believed the Mountain View, Calif., company was in the clear.

But Makan Delrahim told senators the feds could investigate Google’s use of the Android mobile operating system, two sources at the hearing said. The FTC hasn’t investigated Android.

“I think Makan’s comment were fairly significant,” one of the sources said.

Department of Justice officials could not be reached for comment.
