As the government shutdown extends into its fourth week, a heated debate over military pay is exposing fractures within the Republican Party and testing its unity under President Donald Trump's leadership.

A number of GOP lawmakers are voicing concerns over President Trump's maneuvers to bypass Congress to ensure military personnel are paid during the shutdown. Senator Jerry Moran of Kansas, a Republican appropriator, emphasized the importance of adhering to constitutional and legal processes, stating, “While it’s a desired outcome, there’s a process that’s required — by Constitution and by law — for Congress to be not only consulted but engaged.”

Echoing Moran's sentiments, Senator Lisa Murkowski (R-Alaska), also a member of the Appropriations Committee, criticized the lack of respect for established procedures, such as appropriations and reprogramming of funds, which are traditionally handled through Congress.

According to White House officials, who spoke on condition of anonymity, if Congress fails to act before the next military pay date at the end of the month, Trump plans to continue using alternative funding sources to cover military paychecks. This has left top congressional appropriators puzzled over the available funds and frustrated by the administration's failure to submit formal requests to reprogram money.

The Senate is expected to vote this week on a bill proposed by Senator Ron Johnson (R-Wis.) that aims to pay the military and certain other federal workers. However, it is anticipated that Democrats will block the bill's progress. In a separate move, Senate GOP leaders are contemplating another vote on a defense appropriations bill, which previously did not receive enough Democratic support to pass.

Additionally, the White House is reportedly seeking funds to cover shortfalls in other politically popular programs, including agricultural loans—a key concern for Senate Majority Leader John Thune, as highlighted by Trump administration officials.

Other Developments to Watch:

— Republican Unity Efforts: Senator Johnson is set to hold a conference call with House Republicans to encourage solidarity against Democratic opposition and to support staying out of Washington until the Senate acts to reopen the government. President Trump is also scheduled to host a luncheon for Republican lawmakers to express gratitude for their ongoing support during the shutdown and for their efforts in confirming his nominees.

— Redistricting in North Carolina: In a move that could impact the political landscape, North Carolina Republicans are expected to approve a new congressional map this week. This could jeopardize the seat of Democratic Representative Don Davis and is part of broader efforts by Trump and national Republicans to strengthen the GOP majority ahead of the 2026 midterm elections.

As the shutdown and these legislative battles continue, the GOP faces a test of its ability to govern cohesively amid internal disagreements and external pressures.
