The American president has gone against the advice of senior officials in his own party and endorsed a controversial Florida proposal to import drugs from Canada.

“And now [drug prices are] going to be going down a long way further, including the fact that we may allow states to buy drugs in other countries if we can buy them for a lesser price — substantially less price,” Trump said last week at a White House event. “So we will allow them, with certain permissions, to go to other countries if they can buy them for 40, 50, 60 percent less.”
