Arianna Huffington: Uber's Kalanick is 'evolving'

Embattled Uber CEO Travis Kalanick is the "heart and soul" of the ride-hailing giant and should not step down, Uber board member and Thrive Capital founder Arianna Huffington said Monday. "You cannot judge people by their worst moments, (Kalanick) is changing, he's evolving," she told CNN, adding that "we would not be where we are without Travis," a reference to how the company took on taxi associations and city lawmakers to push its disruptive tech. Huffington also is involved in an ongoing investigation into accusations by former engineer Susan Fowler that Uber's environment is a toxic workplace for women. Former U.S. attorney general and Uber advisor Eric Holder is leading that investigation, which should conclude by the end of April, Huffington said. Beyond the internal probe into the company's frat-like culture, Uber also is contending with a lawsuit from Google-owned Waymo over alleged theft of proprietary self-driving car sensor technology.
