New Congress Faces Massive Policy Agenda

With the swearing-in of members of the 119th Congress on January 3, Republicans now control both the Senate and the House of Representatives. When President-elect Donald Trump takes the oath of office on January 20, Republicans will have full control of Washington for the first time since 2018.

The president-elect and Republican leaders on Capitol Hill have outlined a massive policy agenda, including sweeping immigration reforms, wide-ranging tariffs on imports, a massive tax bill, major cuts to government spending, raising the debt ceiling and more—all of which could have a significant impact on the economy, the markets and investors. But narrow margins in Congress and internal party divisions could complicate that agenda.

Here's a look at the political lay of the land as 2025 begins, and how key policy issues may unfold in the coming months.

Republicans face narrow majorities on Capitol Hill

Republicans will have a manageable 53-47 majority in the Senate. That's far short of the 60-vote supermajority needed to bypass a filibuster, however, and there are perhaps a half-dozen Republican senators with independent streaks that could buck the party line on occasion.

But it's the House of Representatives where Republicans' biggest challenges lie. The year began with Republicans holding a narrow 219-215 margin, with one vacancy. But two sitting House Republicans have been nominated for positions in Trump's administration—Rep. Mike Waltz (R-Fla.) as national security advisor and Rep. Elise Stefanik (R-N.Y.) as ambassador to the United Nations. Both will resign from Congress once they are confirmed later this month, leaving two additional vacancies. That will leave Republicans with a razor-thin 217-215 majority until the vacancies are filled via special elections in April. That is a one-seat majority; if Democrats stay unified and a single Republican votes with them on a bill, the resulting 216-216 tie means the bill is defeated under House rules. Keeping all House Republicans on the same page has proven enormously difficult over the past two years, but that's what will be needed to move forward on legislation.
