Trump warns 'sick' South American leader, reiterates 'we need Greenland' for national security

President Donald Trump on Sunday issued warnings about Colombian President Gustavo Petro’s political future and renewed threats to annex Greenland.

Trump, speaking to reporters aboard Air Force One, was initially responding to questions about a U.S. military operation in Caracas that resulted in the capture of Venezuelan leader Nicolás Maduro and his wife, Cilia Flores, as well as the future of Venezuela, when he shifted his focus to another South American country.

"Colombia's very sick too, run by a sick man who likes making cocaine and selling it to the United States. And he's not going to be doing it very long. Let me tell you," Trump said.
