Early Uber investor and former board member Shervin Pishevar is speaking out against Benchmark again. This time, he penned a letter to Uber’s board, demanding that Benchmark Capital drop its lawsuit against former CEO Travis Kalanick. He also filed a motion to intervene in the lawsuit, saying he had “no choice.”

The letter says Pishevar has “tried in every way possible to convince my friends at Benchmark to drop this lawsuit, to end their public campaign against the founder and the company and to divest their shares under a proposal which would reward them hugely for their investment.” But Benchmark has “refused to meet” with Pishevar.
