Travis Kalanick--a vocal fighter against taxi lobbyists, government regulations, pink mustache businesses, and tech giant Google--is speaking out again.。

Uber's former CEO filed a 15-page response to investor Benchmark Capital's lawsuit against him this week. The venture capital firm accused Kalanick of fraud, breach of contract, and breach of fiduciary duty in a lawsuit filed last week.。

Among Kalanick's statement of facts is a note that his mother had been killed in a boating accident when Benchmark was planning to oust him as CEO.。

"It executed its plan at the most shameful of times: immediately after Kalanick experienced a horrible personal tragedy," the 15-page document, first reported by 。 Axios

Thanks for signing up!。

"On June 20, 2017, not more than a week after having expressed 'support' for Kalanick as CEO, and a week and a half after his mother's funeral, Benchmark sent its principals Peter Fenton and Matt Cohler to Kalanick's hotel room in Chicago with a demand that he immediately resign as CEO. They threatened to launch a public campaign against him if he refused," the filing reads. 。

Benchmark's lawsuit includes taking away the three board seats that Kalanick controls, which the firm believes Kalanick does not deserve. Kalanick was ousted as CEO in June, shortly after taking a leave of absence.。

All this drama happened right after his company acquired Otto. Uber made its founder, Anthony Levandowski, formerly of Google, head of self-driving. But now Levandowski and Kalanick are in the middle of a lawsuit with Google's Waymo, which claims that Levandowski stole intellectual property from his former employer.。

As to Benchmark wanting to take away his power, Kalanick argues that it's not reasonable on multiple counts. For one, Kalanick says that his agreement to resign was not co-signed.。
