If prescription savings are to be passed on to Americans not on Medicare, Congress likely would have to pass a law to enact any price reductions.

This is misleading. Prices for most prescription drugs — unbranded generics are the exception — are higher in the U.S. than they are in other high-income countries.

Toward the end of his first Administration, Trump signed a similar Executive Order aimed at lowering the prices of some drugs administered in doctor’s offices; that move was blocked by a court order.
