Since the United States government, under the Trump administration, announced intentions to intervene in Greenland, questions have arisen regarding the extent of Congress's authority to limit presidential power. These proposed interventions follow similar actions in Latin America, including the capture of Venezuelan President Nicolás Maduro, and have sparked debate, particularly within the Republican party, about executive overreach.

The Trump administration's focus on Greenland, a NATO member and long-time ally, has prompted concern on Capitol Hill. According to Annie Grayer, a senior reporter at CNN, even some Republicans are beginning to express unease about the president's unilateral actions. These concerns center on whether Congress can effectively act as a check on the executive branch, especially during President Trump's final term.

The administration's interest in Greenland is not new. In 2019, President Trump reportedly explored the possibility of purchasing the territory from Denmark, an idea that was swiftly rejected by the Danish government. The recent threats of intervention have renewed discussions about the United States' relationship with Greenland and the limits of presidential authority in foreign policy.

The specific policy details of the proposed intervention remain unclear, but the administration's actions in Venezuela offer some insight. The capture of President Maduro was carried out through executive action, bypassing congressional approval. This has led to concerns that the Trump administration may attempt a similar approach with Greenland, potentially leading to a constitutional crisis.

The debate over Greenland highlights a broader tension between the executive and legislative branches regarding foreign policy. While the president has significant authority in this area, Congress retains the power to declare war, ratify treaties, and control funding. The question is whether Congress will be able to effectively use these powers to restrain the Trump administration's actions in Greenland.

Protests have already begun in response to the administration's statements. On January 14, 2026, protesters carrying Greenland flags gathered outside the U.S. Embassy in Copenhagen, Denmark, under the banner "Greenland Belongs to the Greenlanders." The current status of the situation remains fluid, with Congress likely to debate the issue in the coming weeks. The next developments will depend on the administration's next moves and Congress's response.
