A group of bipartisan lawmakers introduced legislation to block President Donald Trump from invading a NATO country or territory, including Greenland.

NATO is talking about improved Arctic security, says the alliance's secretary general. Some of those talks reportedly involve a European troop presence in Greenland. It's a remarkable turnaround for an alliance that has until recently tried to ignore the region.

The Trump administration has repeatedly said the U.S. should be in control of Greenland, which is part of Denmark and NATO.

Britain is discussing with NATO allies how to enhance Arctic security against Russia and China. Transport Secretary Heidi Alexander said Sunday that these talks are routine and not a response to U.S.

Top Trump aide Stephen Miller says it's the "formal position" of the White House that Denmark's territory of Greenland "should be part of the U.S."

The comments followed media reports that the UK was in talks with its European allies about deploying a military force to Greenland.

Speaking during a traditional New Year press conference, Meloni said the use of military action in Greenland would not be in anyone's interest and would have serious consequences for NATO.

The response comes amid concerns over Russia's continued military build-up in the region and its close ties to China.
