Elon Musk says he will find a new leader for Twitter

Musk made the remarks while testifying in a Delaware court to defend against claims that his $56 billion pay package at Tesla Inc was based on easy-to-achieve performance targets and was approved by a compliant board of directors.

Tesla investors have been increasingly concerned about the time that Musk is devoting to turning around Twitter.

Shares of Tesla fell 3% at midday.

"There's an initial burst of activity needed post-acquisition to reorganize the company," Musk said in his testimony. "But then I expect to reduce my time at Twitter."

Musk also admitted that some Tesla engineers were assisting in evaluating Twitter's engineering teams, but he said it was on a "voluntary basis" and "after hours."

The billionaire's first two weeks as Twitter's owner has been marked by rapid change and chaos. He quickly fired Twitter's previous chief executive and other senior leaders and then laid off half of Twitter's staff earlier this month.

Musk sent an email to Twitter employees early Wednesday, telling them they needed to decide by Thursday whether they wanted to stay on at the company to work "long hours at high intensity" or take a severance package of three months of pay.
