Jan. 16 (UPI) -- President Donald Trump said Friday that he may add tariffs to countries that oppose his plan to take over Greenland, which is under the control of Denmark, a NATO member.

He made the remarks during a White House roundtable on rural healthcare. He was talking about threatening European countries with tariffs if they didn't pay more for prescription drugs.

"I went through country after country," Trump said. "I just went one after another."

"I may do that for Greenland on countries if they don't go along with Greenland because we need Greenland for national security," he said.
