Sam Bankman-Fried, the former CEO of FTX, has denied allegations of using a smuggled phone to tweet from a low-security federal prison in Los Angeles. Bankman-Fried, who is serving a 25-year sentence for a multi-billion-dollar fraud, claims that a friend with access to his login details is responsible for posting his messages. The Bureau of Prisons strictly prohibits contraband phones, allowing only approved communication channels. This denial comes amid past incidents at the facility, including a 2014 conviction of a former officer for smuggling a cellphone to an inmate.
