President Trump has apparently not just been mulling over the idea of adding territory to the United States. He might want to get rid of some, too.

Trump this week abruptly called off a meeting with Denmark over its prime minister's "very not nice" remark that his idea of buying Greenland was "absurd," and The New York Times reports that a potential Greenland purchase has been on the president's mind for "more than a year." He also told his National Security Council to look into it.

But that's not all. The Times reports that last year, Trump "joked in a meeting about trading Puerto Rico for Greenland," as he was "happy to rid himself" of it.

Though not a serious suggestion, Trump's joke may have had a kernel of truth in it, as he has on numerous occasions feuded with Puerto Rico's leaders and labeled them "grossly incompetent." He has, in particular, repeatedly gone after San Juan Mayor Carmen Yulín Cruz, who has slammed his administration's response to Hurricane Maria as a "historic failure." Trump has defended his Maria response and last month praised himself for doing a "great job" while declaring that he is "the best thing that ever happened to Puerto Rico." He added, "I have many Puerto Rican friends." Brendan Morrow
