SpaceX Chief Executive Officer Elon Musk pursued women working at the company for sex, including a former intern, the Wall Street Journal reported, citing affidavits signed by one of the women and other interviews.

Former SpaceX executives told the Journal that company policies aren’t enforced with Musk, and that contributes to a culture of sexism and harassment. President Gwynne Shotwell disagreed with that assessment, telling the newspaper that SpaceX fully investigates all complaints of harassment and takes appropriate actions in response.
