Trump says he will order that the U.S. pay only the price other nations do for some drugs

President Trump says he'll sign an executive order on Monday that, if implemented, he says could bring down the costs of some medications. It is an attempt to revive a program he tried and failed to implement during his first term.

The order Mr. Trump is promising will direct the U.S. Department of Health and Human Services to tie what Medicare pays for medications administered in a doctor's office to the lowest price paid by other countries. 

"I will be instituting a MOST FAVORED NATION'S POLICY whereby the United States will pay the same price as the Nation that pays the lowest price anywhere in the World," the president posted Sunday on his social media site, pledging to sign the order on Monday morning at the White House.
