Elon Musk says he's raised the funding to buy Twitter

Elon Musk says he has raised $46.5 billion to purchase Twitter, and is considering buying shares directly from investors to take control of the social media company.

In a securities filing, the Tesla CEO said he raised $22.5 billion from Morgan Stanley Senior Funding to finance the bid, and committed to paying for the rest by selling equity. 

Musk last week proposed to buy Twitter for $54 a share, far above the share price at the time of about $46. But a major Twitter shareholder, Saudi prince Al Waleed bin Talal, called the offer insufficient, and two days later, Twitter's board adopted a so-called poison pill to block Musk's acquisition.
