Fox News senior medical analyst Dr. Marc Siegel weighs in on President Donald Trump's pharmaceutical executive order aiming to cut drug prices for Americans.

President Trump will hold a press conference Monday morning with Health and Human Services Secretary Robert F. Kennedy Jr. to announce an executive order to cap prescription drug and pharmaceutical prices at the lowest cost offered in any other country.

The order is based on a "most favored nation" pricing model, which is similar to a policy Trump pushed in his first administration.
