Thursday brought a series of new signals that at least a small number of ideologically varied Republican lawmakers are growing frustrated with the war in Iran and with the administration’s frequently shifting rhetoric about it — including from some otherwise-hawkish lawmakers.

Sen. Lisa Murkowski (R-AK), who previously called for an end to the war, told Bloomberg on Thursday that she’s working on a potential authorization for use of military force in Iran, to limit the scope of the U.S. operation and prevent the deployment of ground troops.

“I don’t know what else to do,” Murkowski told the outlet. “I’m worried we get out of town and the president goes in with ground troops aiming for a full takeover.” The Senate is scheduled to be in recess for the next two weeks.

After Murkowski’s comments, The Wall Street Journal reported that President Donald Trump was considering deploying an additional 10,000 troops to the Middle East.

Rep. Don Bacon (R-NE), who has generally been supportive of the war effort, told NOTUS on Thursday after a House Armed Services Committee briefing the day prior that he was unclear on the U.S.’ plans and goals in the war.

“I don’t know the plan,” Bacon said. “What is the end-state goal? What is the mission? I think clarity there would be helpful.”

Rep. Rob Wittmann (R-VA) also told the outlet that he’s seeking “more granularity, more specificity on what specifically is happening on the ground, and then how is that leading to achieving the military objectives.”

Rep. Mike Rogers (R-AL), the Armed Services Committee chairman, emerged from the briefing Wednesday frustrated with what he said was a lack of information from the administration, warning officials that their reticence could have “consequences.”

Meanwhile, Rep. Nancy Mace (R-SC), who’s been more critical of the war in general, indicated to Axios she’s now inclined to vote for an upcoming war powers resolution to end the war, bringing it closer to the threshold for passage. She added, “War with Iran needs to end. President Trump has won the war, time to exit.”

House Democrats were initially expected to call a vote on that legislation this week, but have delayed their plans until after the congressional recess, saying they still don’t think they have the votes to pass it.

Regardless of whether the resolution passes the House, it remains unlikely to pass the Senate and could be vetoed by Trump. But passage of the resolution in the closely divided House would be a rebuke of Trump and his strategy.
