President Donald Trump on Thursday announced the launch of TrumpRx — a direct-to-consumer website that is key to his administration's efforts to lower prescription drug costs in the U.S. The president said millions of Americans would save money through the platform. But it's still unclear if all patients — particularly those with insurance coverage — will see more cost savings from using that site to buy their medicines than they would through existing methods. TrumpRx targets people who are willing to pay with cash and forgo insurance, which suggests that patients without or with limited coverage may benefit the most.
