Some of Uber’s top investors appear to be engaged in a civil war, underscoring the deep chaos that has sown behind the scenes.

Just a day after Benchmark Capital Partners sued former Uber CEO Travis Kalanick, another faction (of unknown size) led by investors Shervin Pishevar has asked that Benchmark call off its lawsuit, resign its board seat, and sell a substantial portion of its holdings in the ridesharing company.

According to Pishevar, Benchmark’s lawsuit has "held the company hostage to a public relations disaster." In a letter, the investor even warned that an "escalation of this fratricidal course" would "interfere with fundraising" and the ongoing search for a new chief executive at Uber.

The letter was first published on Twitter by Axios and by Mike Isaac of The New York Times.

Pishevar did not immediately respond to Ars’ request for comment.
