Pennsylvania Senator John Fetterman has expressed openness to discussing the U.S. purchasing Greenland, likening the idea to the 1803 Louisiana Purchase. During an interview on Tuesday, Fetterman clarified he does not support taking Greenland by force but sees a potential “responsible conversation” about buying it. His comments come amid renewed attention to President-Elect Trump’s suggestion that the U.S. should control Greenland for national security purposes.
