Senior Senate Democrats have requested a hearing on the Trump family's crypto venture, World Liberty Financial, and its connections to the Abu Dhabi royal family. This follows reports that an Abu Dhabi investment vehicle secretly acquired a 49% stake in the company, with $187 million directed to Trump-controlled entities. Trump claims no involvement in the investment. Democratic senators, including Elizabeth Warren, have urged Congress to investigate the investment's potential influence on Trump's decisions. They also seek a national security review by the Treasury. As Congress progresses on a federal crypto regulation bill, some Democrats demand ethics provisions before offering support.
