President Donald Trump announced Sunday that he plans to resurrect a controversial policy from his first term that aims to reduce drug costs by basing payments for certain medicines on their prices in other countries.

The president is planning Monday to revive a plan from his first term, which would peg the prices the United States pays for drugs to the amounts paid in other countries, which tend to be lower.

The president announced an executive order aimed at lowering U.S. drug costs, revisiting an idea that was blocked in court during his first term.
