Uber CEO Travis Kalanick is not the first exec to deal with sexual harassment and sexism issues. And he’s not the first to be accused of stealing technology. He’s also not the first to anger customers through cloddish statements. And he’s not the first to face significant doubts about his ability to manage a fast-growing startup.

But he is the very first speaker in the 15 years we have been putting on our tech and media events to cancel his interview due to the many embarrassing issues at his company. In this case, because the report from former Attorney General Eric Holder on Uber’s culture and management problems has been delayed until the week of Code at the end of May.

This clearly shows he wouldn’t be able to answer the tough questions Kara Swisher would have asked him.
