If Donald Trump thought he was settling the GOP’s most important strategy dispute, Senate Republicans are not getting the message.

Less than 24 hours after Trump endorsed “one powerful bill” to carry his domestic policy agenda, a dozen senators said in interviews that the legislative path to its enactment remains an open question. It underscores the mounting confusion as Republicans feel pressure to show quick progress on border, energy and tax priorities.

As Republicans settle into their new majorities in both the House and Senate, the party is planning to act swiftly to secure early wins that will allow President-elect Donald Trump to advance his agenda quickly.

However, Republicans still need to agree on what matters to prioritize before they can get the wheels turning in the 119th Congress. Although they’ll hold control of Congress, their slim margins in both chambers will make it easier said than done to achieve the aggressive changes Trump is hoping to implement after he takes office on Jan. 20, 2025.

Republican senators battled behind closed doors Tuesday over a proposal to beef up Social Security benefits for people who are eligible for non-Social Security government pensions.

The legislation, which has passed the House, is expected to reach the Senate floor Wednesday, but some Republicans who are worried about its price tag are hoping to stop it dead.

One GOP senator who attended Tuesday’s meeting described it as “an intense discussion.”

Republican senators fear that the narrow House GOP majority in next year’s Congress could rain chaos on President-elect Trump’s agenda and are pushing to finish up work on the overdue annual appropriations bills before Trump takes office on Jan. 20.

Speaker Mike Johnson (R-La.) has insisted on punting the annual spending bills into March of next year, but GOP senators worry that’s a big strategic mistake.

National security-minded Republican lawmakers are alarmed by what they see as a growing split between themselves and former President Trump on key issues, including the war in Ukraine, preserving the NATO alliance and protecting Taiwan from Chinese aggression.

Trump’s actions over the past three weeks have stirred confusion and concern among Republican senators who voted earlier this year to approve tens of billions of dollars to contain Russia’s invasion of Ukraine and to deter China from attacking Taiwan, an important U.S. ally and trading partner.
