"Our nation's prosperity is built on a foundation of fair competition and open markets. But right now we're facing a monopoly problem as dominant digital platforms - some of the most powerful companies the world has ever known - increasingly give preference to their own products and services. It's past time to put in place rules of the road to give small businesses and entrepreneurs a chance to compete and bring down costs for all consumers who rely on digital platforms. I won't stop fighting to get this done."
