Amidst growing concerns over potential executive overreach, questions are being raised about Congress's ability to check President Donald Trump's interest in Greenland. The Trump administration, fresh from its intervention in Venezuela and the capture of President Nicolás Maduro, has openly discussed similar actions in other parts of Latin America, but Greenland, a NATO member and long-time U.S. partner, has become a particular focus of the president's attention.

These threats, largely communicated through unilateral executive actions, have sparked debate on Capitol Hill, with even some Republicans expressing unease as Trump enters his final term. Annie Grayer, a senior reporter at CNN, discussed the congressional response and emerging divisions within the Republican party on the "Today, Explained" podcast.

The specific nature of Trump's interest in Greenland remains somewhat unclear, but the administration's public pronouncements have fueled speculation about a potential U.S. attempt to acquire or exert greater control over the territory. This has prompted protests, such as the "Greenland Belongs to the Greenlanders" demonstration outside the U.S. Embassy in Copenhagen on January 14, 2026.

The U.S. has a long history of strategic interest in Greenland, particularly due to its location and potential resource wealth. During the Cold War, the U.S. maintained a significant military presence on the island, and the Thule Air Base remains a crucial component of U.S. missile defense systems.

The current situation highlights the ongoing tension between the executive and legislative branches regarding foreign policy decision-making. While the president traditionally holds significant authority in foreign affairs, Congress retains the power to check the executive through legislation, appropriations, and oversight.

It remains to be seen whether Congress will take concrete action to limit the president's options regarding Greenland. The emerging divisions within the Republican party suggest that some members may be willing to challenge the administration, but the extent of their opposition and its potential impact are still uncertain. The coming months will likely determine the future of U.S.-Greenland relations and the balance of power between the executive and legislative branches in shaping foreign policy.
