President Donald Trump holds roughly 41% of Trump Media through a revocable trust managed by his family, and the senators argued he stands to profit from the service. They warned that high-frequency trading firms, which rely on executing trades in fractions of a second, stand to gain the most. The senators quoted their own letter to make the point: "While financial firms and analysts have relied on manual monitoring of Truth Social, the API automatically feeds around-the-clock Truth Social posts directly to those who are simply willing to pay up front for milliseconds of additional notice."
