Neil DeGrasse Tyson is defending Elon Musk. The celebrity scientist spoke on CNBC Wednesday and gave his thoughts on the Tesla CEO. Musk has come under fire recently for a controversial tweet about taking Tesla private, and for smoking pot on Joe Rogan's podcast. Tyson said Musk needs to comply with the Securities and Exchange Commission since Tesla is a publicly traded company. But beyond that, he said, let the man be an individual. Tyson, who's a Harvard graduate, said he went to a highly selective college where people were really smart and really weird, and the weirdness became an element of their behavior that he just came to expect.
