Earlier court filings had indicated Musk would be deposed starting on Sept. 26, while a filing Saturday said Agrawal was also due to be questioned starting Monday morning. That day, Musk’s team learned of Agrawal’s rescheduling, the person said. Agrawal’s deposition could be a chance for Musk’s team to question him about Zatko’s whistleblower allegations. Agrawal also turned down an invitation to testify at a Senate committee hearing alongside Zatko earlier this month citing the litigation with Musk, according to Sen. Chuck Grassley. Twitter and Musk are set to go to trial over the acquisition dispute in mid-October.
