Elon Musk appoints new CEO of "Twitter"

Twitter CEO Elon Musk said Thursday that he had appointed a new CEO of the social media platform and that she would start working in about six weeks.

"My role will move to the position of executive chairman and chief technology officer, overseeing products, software and computers," he said in a tweet.

The move is likely to calm the fears of Tesla investors, who have been increasingly worried about Musk's time to make changes to Twitter.

Tesla shares jumped 2.4 percent on the news.
