About

Served as an Assistant United States Attorney for the prosecution, conducting direct and redirect examinations of several government witnesses and later presenting arguments about the defendant's knowledge, conduct, and asserted explanations.

On Days 2 and 3, Sassoon examined Adam Yedidia on direct and redirect. During Yedidia's cross-examination, she raised a problem with a defense question, and the court told defense counsel that the same problem remained through each iteration. She examined Caroline Ellison on direct across Days 5 and 6 and on redirect on Day 7, and she conducted Shamel Medrano's direct examination on Day 11.

In argument to the jury, Sassoon emphasized that the government bore the burden of proof beyond a reasonable doubt and asserted that it had met that burden. She used Government Exhibits 5, 36, and 50 to argue that contemporaneous spreadsheets conflicted with the defendant's account of when he learned about Alameda's special credit treatment and multibillion-dollar liability.

Sassoon also asked jurors to assess the defendant's claimed lack of knowledge against his role, major expenditures, relationships with senior employees, financial materials, and assertedly inconsistent testimony. She argued that later fundraising, public assurances, and November conduct supported knowing participation in concealment even if jurors accepted his alternative timing account. Anticipating the court's instruction, she separately argued that deliberate avoidance of obvious facts about customer deposits, Alameda's treatment, and the fiat-account discrepancy could establish knowing conduct.

In argument to the jury, Sassoon challenged the defendant's account of his knowledge. She relied on Government Exhibits 5, 36, and 50, his role and relationships, major expenditures, financial materials, and asserted inconsistencies in his testimony. She also argued that later fundraising, public assurances, and November conduct supported knowing participation in concealment even under his alternative timing account.

Summary

The prosecution's rebuttal challenged the defense's good-faith and credibility arguments, emphasized documentary and witness corroboration, and argued that conscious avoidance or later knowing participation independently supported guilt.
