Elon Musk will join Twitter’s board of directors, the social network’s chief executive announced Tuesday, a day after the Tesla boss bought a major stake in the company and became its largest shareholder.

“I’m excited to share that we’re appointing @elonmusk to our board! Through conversations with Elon in recent weeks, it became clear to us that he would bring great value to our Board,” Twitter CEO Parag Agrawal said in a tweet.
