Secretary of Transportation-designee Elaine Chao said Wednesday in her confirmation hearing President-elect Trump hasn’t taken a position on privatization of air traffic control systems. That may have come as a surprise after Rep. Bill Shuster, chairman of the House Transportation Committee, told reporters Trump was on board with the plan.
