In a courtroom drama minus the jury, Sam Bankman-Fried (SBF) took the stand for what can be best described as a “test run.” The hearing aimed to help the judge decide what evidence will be admissible in the actual trial. SBF's performance under Assistant U.S. Attorney Danielle Sassoon's questioning was less than stellar. His verbose answers and frequent apologies contrasted sharply with Sassoon's pointed questions, at times making him appear evasive. The hearing also touched on SBF's use of encrypted messaging app Signal and his company's data retention policy.
