The city of Portland, Oregon, is starting its own investigation of Uber Technologies Inc.’s use of software to evade regulators while a U.S. Justice Department criminal probe continues in that city along with Philadelphia and Austin, Texas, according to officials.

The Portland City Council voted Wednesday to subpoena San Francisco-based Uber seeking information about the so-called Greyball program that wasn’t provided by the ride-hailing company in an earlier audit by the city’s transportation department.
