The second Presidency of Donald Trump is challenging the separation of powers in the United States, as the administration defies the courts and utilizes emergency powers to control aspects of policymaking normally designated to Congress. The courts – all the way up to the Supreme Court – have stressed the importance of adherence to the rule of law, but the responses to court rulings by the administration on issues ranging from due process to releasing federal funds seem to be setting the stage for a showdown between the President and the Supreme Court. The Congress, currently controlled by the Republicans, has so far been unwilling to check Presidential power. However, concerns have surfaced among Republican elites over the impact of Trump’s policies on the electoral prospects of his party. How has the challenge posed by the Trump administration unfolded since his inauguration? How unprecedented are the current tensions between the White House and other branches of government? What are the possible future implications of the approach pursued by the administration?
The US Research Day 2025 is organised by the Center on US Politics and Power (CUSPP) at the Finnish Institute of International Affairs (FIIA).
