According to ChainCatcher, former FTX US President Brett Harrison tweeted that he worked with the "emotionally unstable" SBF during his tenure, and his relationship with SBF and his deputies had completely deteriorated. The dispute between the two sides over FTX's management style lasted for months.
Harrison added, "I didn't expect that these problems would lead to billions of dollars of fraud. In my career, I have seen similar problems in other more mature companies and believe that these problems will not have a fatal impact on business success." In addition, he also said that according to public information, the plan was obviously closely controlled by SBF and his core circles in FTX.com and Alameda, and Harrison and other FTX US executives were not involved.
