Republican lawmakers are starting to urge President Trump to reverse his decisions to pause U.S. military and intelligence assistance to Ukraine, warning that a prolonged stoppage of U.S. help for the war effort would have a seriously detrimental effect.

They say that Trump has the right to temporarily halt weapons shipments to Ukraine to assess the war, pressure NATO allies to step up their contributions and to create a window to negotiate a peace deal with Russian President Vladimir Putin and Ukrainian President Volodymyr Zelensky.

President Trump’s continuous back-and-forth on tariffs is taking a toll on Republican lawmakers who admit the constant announcements are difficult to follow even as they try to assuage concerns from constituents.

Trump’s six weeks in the White House have been a roller coaster on a number of fronts. But tariffs have topped that list as Trump has threatened to impose them on numerous U.S. trade partners, delayed their implementation, gone through with enacting them, hinted at compromises and carved out exceptions.

Republican lawmakers are urging President Trump to salvage negotiations with Ukrainian President Volodymyr Zelensky in hopes of reaching a peace deal that halts Russian encroachment and possibly gives the United States access to Ukraine’s rich mineral wealth.

GOP senators say they hope Trump and Zelensky can put Friday’s heated exchange in the Oval Office behind them, recognizing that continued U.S. support for Ukraine is critical to maintaining Kyiv’s leverage in peace talks with Russian President Vladimir Putin.

Republicans on Capitol Hill are divided over tech billionaire Elon Musk being the public face of President Trump’s aggressive bid to shrink the government, with some souring on Musk’s prominent role as he increasingly has become a target of Democratic attacks.

Several GOP senators worry that having an unelected billionaire crow about slashing federal jobs, which happen to employ many people in their home states, is not a good look when inflation remains a major problem and many Americans are having trouble making ends meet.

Senate Republicans are urging President Trump to respect the rulings of federal judges who have blocked his executive actions to freeze spending federal grants and loans, dismantle the U.S. Agency on International Development (USAID) and ban birthright citizenship.

GOP lawmakers have been reluctant to criticize Trump’s actions, fearing it could make them targets for primary challenges next year.

But they are growing increasingly worried about the nation plunging into a constitutional crisis if Trump ignores court orders halting his most aggressive actions.

President-elect Trump wants congressional Republicans to figure out a way to avoid a default on the national debt after venting his frustration with the Senate GOP over their failure to raise the debt limit as part of a government-funding package last month.

Trump told Senate Majority Leader John Thune (R-S.D.) at a recent meeting that it’s now up to him to find a way around the debt-limit impasse, according to a Republican source familiar with the conversation.

Senate Republicans fear that President-elect Trump’s tax agenda could be derailed in the House by several potential landmines, including calls by some GOP lawmakers to raise corporate taxes and to lift the cap on state and local tax (SALT) deductions.

Senators worry that if one or two House Republicans insist on raising corporate taxes to cut the deficit and a few others insist on substantially raising the cap on SALT deductions, Trump’s broader $4.5 trillion tax initiative may stall.
