KEY POINTS
  • Sam Bankman-Fried should be barred from encrypted messaging software, including Signal, over fears of possible witness tampering, federal prosecutors said in a letter to a Manhattan judge.
  • Prosecutors claim that Bankman-Fried's overtures to FTX US general counsel Ryne Miller constituted a possible attempt at witness tampering.
  • The government cited previously unreleased testimony from former Alameda CEO Caroline Ellison as part of their justification for the ban.

Federal prosecutors are attempting to bar indicted FTX co-founder Sam Bankman-Fried from using encrypted messaging software, citing efforts that may "constitute witness tampering," according to a letter filed in Manhattan federal court Friday.

Bankman-Fried reached out to the "current General Counsel of FTX US who may be a witness at trial," prosecutors said. Ryne Miller, who was not identified by name in the government filing, is the current counsel for FTX US, and a former partner at Kirkland & Ellis.
