Representative Ro Khanna has initiated an investigation into a $500 million stake acquired by a UAE royal family's investment vehicle in World Liberty Financial, a Trump-associated crypto company. Concerns focus on whether this transaction influenced the Biden-era export restrictions on advanced AI chips to the UAE, which were later reversed under the Trump administration. The inquiry demands disclosures on the deal's structure, payment flows, and any influence on US policy decisions, raising national security and ethical questions.
