Congress returned to Washington on Monday facing a politically charged six-week session after Democrats’ sweeping midterm victory reshaped the balance of power in the capital. Although Republicans retain control until the new Congress is sworn in on January 3, 2027, the election has changed the atmosphere surrounding negotiations and the final legislative decisions of the year.

Among the most urgent responsibilities is preventing a lapse in federal government funding. Lawmakers must also consider an annual defence policy bill, energy permitting legislation and President Donald Trump’s judicial nominees before the current session ends. The funding deadline in mid-December gives congressional leaders limited time to negotiate an agreement.

The Associated Press reported that Democrats arrived with renewed confidence after winning control of both chambers in the November 3 elections. Republicans, meanwhile, are confronting questions about the party’s direction and the political consequences of voter dissatisfaction, particularly over the economy and the cost of living.

Leadership discussions are also expected to intensify. House Republicans face an internal contest involving Steve Scalise and Jim Jordan after Speaker Mike Johnson stepped aside from the leadership race. Senate Republican leader John Thune is expected to continue in his position, now as the leader of the minority party. Democrats are due to make their own leadership decisions later in November, with debate continuing over the future roles of senior figures including Chuck Schumer.

The lame-duck period may also bring contentious oversight debates. The impeachment effort against Defense Secretary Pete Hegseth is one of the issues likely to test party unity and the ability of congressional leaders to control the floor agenda. The dispute is part of a wider argument over the administration’s conduct of the Iran war and the responsibilities of senior defence officials.

For the administration, the immediate challenge is to work with a Congress that is about to become more hostile to its agenda. For Democrats, the coming weeks offer an opportunity to set priorities before taking control, while Republicans must decide which legislative achievements can still be secured before their majorities end.

The session is therefore more than a routine end-of-year legislative period. It is an early test of how Washington will function during a divided transition, with government funding, national security, judicial appointments and party leadership all competing for attention.
