The controversy and the pressure from investors to step aside proved to be too much. Following a leave of absence, embattled Uber CEO Travis Kalanick has stepped down from the company that he helped to create in 2009.  The investors made their demand for Kalanick to step down in a letter delivered to the chief executive while he was in Chicago. In the letter, titled “Moving Uber Forward”, the board stated that he must immediately leave the company. After consulting with at least one board member, he decided to resign. Kalanick will still serve on Uber’s board of directors.
