In his first major action on health care costs this term, President Donald Trump issued a multi-part executive order on Tuesday aimed at lowering drug prices and reducing costs for Medicare. The move comes as his administration seeks to impose tariffs on pharmaceutical imports that many experts have said could lead to drug shortages and price hikes.

A federal judge in Washington, D.C., temporarily blocked Trump's recent executive order aimed at the law firm that has for years represented Dominion Voting Systems.
