After Ilon Musk acquired a 9.2% stake in social network Twitter (NYSE:TWTR), it made him the largest shareholder in the social media platform. But in light of employee concerns about Musk’s appointment to the company’s board of directors, Twitter decided to hold a Q&A session with Musk, Business Insider writes.

Many Twitter employees expressed disappointment over Musk’s involvement with the company.

According to Twitter CEO Parag Agrawal on Thursday, “Since our announcement of Ilon Musk joining the board, many people have had various questions for him, and I want you to ask those questions of him.”

Last month, Musk criticized Twitter for its failure to adhere to free speech principles and undermining democracy.

In his tweet on Tuesday, Agrawal welcomed Musk to the board. In response, Musk said he “looks forward to working with the Twitter board to make significant improvements to Twitter in the coming months.”

An avid Twitter user, Musk is often controversial with his posts, and his outspoken comments have repeatedly sparked controversy.

For example, in 2018, Musk’s tweets even led to the launch of an investigation against him when he wrote that he was considering privatizing Tesla (NASDAQ:TSLA) at $420 per share and that he already had funding secured. The SEC sued him for that tweet, claiming he made “false and misleading statements.” Musk and Tesla settled the lawsuit with the SEC for $40 million.
