The Federal Trade Commission is investigating Elon Musk's mass layoffs at Twitter and trying to obtain his internal communications as part of ongoing oversight into the social media company's privacy and cybersecurity practices, according to documents described in a congressional report. The FTC has been watching the company for years since Twitter agreed to a 2011 consent order alleging serious data security lapses. But the agency's concerns spiked with the tumult that followed Musk's Oct. 27 takeover of the company.
