US lawmakers have launched an investigation into several Wall Street underwriters, including Dominari Securities, whose parent company is linked to the Trump family. The House of Representatives Select Committee on China is seeking information about Chinese initial public offerings (IPOs) they helped underwrite. The companies allegedly used these IPOs to inflate their share prices through coordinated trading and promotion, then dumped shares on retail investors before the stocks crashed. The lawmakers have stated that around $16 billion in US investor wealth has been drained through these schemes. The inquiry seeks documentation from the underwriters including communications, trading records, funding sources, and due diligence policies related to Chinese IPOs.
