According to a company filing with the US Securities and Exchange Commission, Bret Taylor, former chairman of the board, and Parag Agrawal, former chief executive, are among the nine ousted directors.

Musk completed his $44 billion takeover of the social media platform last week after months of legal wrangling.

While Musk might have the most executive authority in the company, he may not have total power. Billionaire Prince Alwaleed bin Talal of Saudi Arabia announced that he was rolling over his $1.9 billion in shares, making him the company's biggest shareholder after Musk.

The Prince is not that well-loved amongst US politicians and the news prompted concern among some politicians, including US Democrat Senator Chris Murphy.

Murphy has since requested the Committee on Foreign Investment to investigate the national security implications of his investment in Twitter.

"We should be concerned that the Saudis, who have a clear interest in repressing political speech and impacting US politics, are now the second-largest owner of a major social media platform," Murphy tweeted.

The whole free speech thing is ironic given that was the reason Musk claimed he wanted to buy the company to allow right wing chums like Donald Trump and Kayne West a platform where they could say what they like. Now if Twitter is a safe haven for those who have views that do not offend fundementalist Muslim Saudis then Musk might be biting off more than he can chew, given that Right-Wing Americans tend to love Muslims in the same way they like homosexuals.

Musk also angered his new born-again Christian fanbase by showing up at a party dressed as Satan, still if the Saudis think it is ok Musk is not going to lose his head over it.
