Senate Republicans are divided over how to respond to an expected request from President Donald Trump to fund and potentially extend the ongoing military conflict with Iran.

Some GOP senators are working with Sen. Lisa Murkowski on a possible authorization framework that would extend war powers beyond the 60–90 day limit under the War Powers Act.

Several Republicans, including Sens. John Curtis, Thom Tillis, and Jerry Moran, are demanding clearer information from the White House on objectives, strategy, and an exit plan before approving additional funding.

Senate Majority Leader John Thune, however, argues that a formal authorization vote may not be necessary if current military objectives are met, and has downplayed immediate concerns, The Hill has reported.

The debate is creating uncertainty around future defense funding, as lawmakers also weigh economic impacts and rising costs tied to the conflict.
