KWAP declined to comment when contacted by Reuters. MaGIC said "we strongly refute involvement in any quid-pro-quo arrangements." The DOJ investigation is the latest in a series of worldwide legal wrangling at Uber, which has also made headlines with allegations of sexual harassment in the workplace and executive misconduct. Last month, Uber appointed Dara Khosrowshahi, who led travel-booking website operator Expedia Inc for 12 years, as chief executive to succeed Travis Kalanick who was ousted in June.
