I write as a deeply concerned constituent to urge immediate congressional action to prevent President Trump from taking further unilateral military or territorial actions—specifically regarding Greenland. On January 3, the U.S. military conducted direct strikes inside Venezuela and captured President Nicolás Maduro and his wife without prior approval from Congress. This operation, which the administration has described as a military strike and then a law-enforcement action, has been widely criticized by legal experts and international authorities as violating international law and norms on state sovereignty, and it appears to have occurred without congressional authorization, contrary to the Constitution’s war powers provisions. Just days later, on January 9, President Trump publicly stated that the United States will take action on Greenland “whether they like it or not,” and that if Greenland cannot be acquired “the easy way,” it will be done “the hard way.” Reports indicate the administration is considering military options, cash incentives to Greenlanders, or other coercive means to secure control of the territory, despite Denmark and Greenland asserting that “Greenland is not for sale.” Taken together, these developments demonstrate a troubling pattern of potential executive overreach in foreign affairs—actions that risk undermining international law, destabilizing NATO alliances, and bypassing the constitutional role Congress holds over war and peace. I therefore urge you to act immediately to: Prohibit any federal funds for military, covert, or operational activities related to Greenland without express congressional authorization. Affirm that the United States respects the sovereignty of allied nations, international law, and established treaty obligations. Reassert congressional authority over the use of U.S. military force, ensuring no president can unilaterally initiate military actions that reshape global norms or provoke conflicts. The Constitution assigns to Congress—not the President—the power to declare war and authorize the use of force. What happened in Venezuela highlights how quickly foreign policy can escalate without proper oversight. Please act now to prevent a repeat scenario with Greenland before it is too late. Thank you for your time and leadership.
