‘That’s their problem’: Trump threatens Greenland's leader after vow to stay with Denmark

President Donald Trump threatened yet another foreign leader on Tuesday during a press gaggle at Joint Base Andrews after returning to Washington, D.C. from a brief trip to Detroit.

Earlier in the day, Greenland Prime Minister Jens-Frederik Nielsen said his country would rather stay as part of Denmark than become part of the U.S. Nielsen's comments come at a time when Trump has upped the ante against Greenland, saying the U.S. needs to control the island nation for its own national security.

Nielsen's comments apparently didn't sit well with Trump, who was asked to respond to them during the press gaggle.

"That's their problem," Trump said. "I disagree with them. I don't know who he is, don't know anything about him, but that's going to be a big problem."

Nielsen is just the latest foreign leader that Trump has threatened in recent weeks. He has also threatened the Colombian President Gustavo Petro and Mexican President Claudia Sheinbaum over their country's drug policies. The threats followed Trump's middle-of-the-night operation to capture Venezuelan President Nicolás Maduro and bring him to the U.S. to stand trial for narco-terrorism charges.

The Trump administration's moves against foreign officials also come at a time when the administration has faced accusations its seeking to distract from the ongoing release of the Jeffrey Epstein files. Recently released files painted Trump's relationship with the disgraced financier and convicted sex criminal in an unsavory light.
