Billionaire investor Ron Baron poured $100 million into Twitter during Elon Musk's takeover of the social media company last year.

In an interview on CNBC Tuesday, Baron said he was promised that he would make "two to three times" his money on the investment. 

"He explained when we made our investment that he saw that there was a lot of cost there. It was incredibly poorly run," Baron said, referring to Musk.
