In brief
The 2026–27 U.S. midterm elections gave Democrats control of both chambers, but analysts warn that ongoing domestic policy disputes will keep the U.S. focused inward. European leaders remain skeptical that the new Congress can swiftly restart comprehensive cooperation, though some cooperation on specific projects is expected.
On January 3, 2027, the new 120th U.S. Congress opened its sessions, bringing a Democratic majority in both the House of Representatives and the Senate after the November 3, 2026 midterm elections. The triumph secured by Democrats has not, however, translated into an immediate revival of transatlantic relations, according to European officials and media reports that followed the electoral outcome.
European leaders, notably those within the European External Action Service, affirmed that they are "under no illusion" that a partisan shift in Washington would automatically undo years of policy divergence. The comments came amid broader concerns that domestic politics will pull the Democratic majority’s attention inward, limiting time for foreign engagement.
The new Congress faces a crowded legislative agenda that includes a 2027 budget reconciliation package, several bipartisan Commitments to Pass Climate legislation, and a host of domestic reforms surrounding immigration, infrastructure, and health care. Analysts note that these busy sessions may leave little room for the kind of comprehensive policy dialogue required to reset U.S.–EU ties after the turbulence of the previous decade.
European officials highlight that the pace of transatlantic conversation often mirrors the prevailing alliance sentiment in Washington, and the current body of legislators has already signaled that internal priorities will dominate. This stance is echoed by a recent commentary from the International Centre for Defence and Security, which states that Democrats’ control "will have significant implications for President …" and underscores a potential reshaping of defense cooperation topics.
Some lawmakers, however, remain hopeful. Several U.S. and EU officials hope that targeted cooperation can resume, citing areas such as trade enforcement, cybersecurity, and intelligence sharing that were previously stalled. The expectation is that the Democratic majority may permit small, incremental steps toward collaborative projects that were frozen before the political uncertainty that surrounded the handover in 2024.
The ongoing tension between domestic political imperatives and foreign policy ambition poses a crucial question for both sides of the Atlantic. The EU has expressed a measured optimism that “projects that were frozen before” can be revived if the incoming Congress prioritizes them. Nonetheless, scepticism about the scope and speed of any normalized engagement remains rooted in the realities of the 120th Congress’s political climate.
Election results also shift the balance of power in U.S. state governments, with gains in key swing states potentially amplifying partisan divisions. The shift could have cascading implications for the political dynamics of American public accountability mechanisms, parliamentarians’ ability to hold executive branches accountable, and the focus on foreign policy issues at the federal level.
Parliamentary bodies on both sides of the Atlantic are watching for changes in the foreign policy agenda. The European Parliament, for instance, anticipates that the U.S. could sign an agreement on specific cooperation in the energy sector, but there remain undercurrent uncertainties regarding the pace at which the new U.S. administration will negotiate its commitments for NATO's annual budget and joint military exercises.
There are also implications for the U.S. judicial system, particularly given that courts will handle an increased array of investigations into expansive GDPR compliance across the United States. The European Union is counting on streamlined communications with U.S. federal courts to clarify cross-border digital policy and the interpretation of CliffsTrack or other new legislation.
Both institutions—Congress and the courts—play pivotal roles in ensuring public accountability and governance, and public expectations are high for the new Congress to demonstrate a commitment to be an engaged partner abroad. If the new lawmakers fail to bring foreign policy to the forefront of their legislative agendas, the EU’s confidence in a democratic U.S. partnership could continue to dwindle.
In sum, while the Democratic majority now controls both chambers of Congress, many in the EU remain cautious that the new Congress will have little time or inclination to address the complex relationship that requires a sustained and dedicated partnership from Washington. The timing of any substantive changes in transatlantic policy will depend ultimately on how the Democratic leadership balances domestic policy goals with the increasing demands for European collaboration.
