Top Republican warns Trump against making a deal with Iran: 'Finish the job'

A top Senate Republican is publicly pressuring President Donald Trump against pursuing what he described as a weak Iran deal as administration officials signal negotiations with Tehran are making progress. 

Sen. Roger Wicker, R-Miss., chairman of the Senate Armed Services Committee, issued a sharply worded warning Thursday urging Trump not to abandon military pressure on the Iranian regime in favor of diplomacy.

"We are at a moment that will define President Trump’s legacy," Wicker said in a statement. "His instincts have been to finish the job he started in Iran, but he is being ill advised to pursue a deal that would not be worth the paper it is written on."

"Our commander-in-chief needs to allow America's skilled armed forces to finish the destruction of Iran's conventional military capabilities and reopen the strait," Wicker went on. "Further pursuit of an agreement with Iran's Islamist regime risks a perception of weakness. We must finish what we started. It is past time for action."

The remarks expose growing tension inside Republican national security circles as the Trump administration weighs whether to pursue a negotiated agreement with Iran or continue its military campaign against the Iranian regime and its nuclear capabilities.

The White House could not immediately be reached for comment.

Wicker’s comments came just hours after Secretary of State Marco Rubio acknowledged there had been "some progress" in ongoing negotiations with Iran, while cautioning that no agreement had been reached.

"There's been some progress," Rubio said Thursday. "I wouldn't exaggerate it. I wouldn't diminish it." 

"We're not there yet," Rubio added. "I hope we get there." 

Rubio said key issues remain unresolved, including Iran’s stockpile of highly enriched uranium and whether Tehran would be permitted any future uranium enrichment capability under a potential agreement.

"The issue of highly enriched uranium has to be discussed. Its disposition has to be dealt with. And of course, the issue of future enrichment has to be dealt with as well," Rubio said.

He also indicated discussions involving the Strait of Hormuz remain part of broader negotiations.

The comments marked one of the clearest public signs yet that active diplomacy between Washington and Iran remains underway despite recent military escalation and fears of a wider regional conflict.

Trump himself recently signaled he remains open to giving diplomacy additional time before considering further military action.

"If I can save war by waiting a couple of days, if I can save people being killed by waiting a couple of days, I think it's a great thing to do," Trump said in recent days.

The administration’s diplomatic push has coincided with intensified regional mediation efforts, including a high-profile visit by Pakistan’s army chief, Field Marshal Asim Munir, to Iran — a trip widely viewed as part of broader backchannel efforts aimed at reducing tensions between Washington and Iran.

The visit fueled further speculation that Pakistan is playing a quiet intermediary role as negotiators explore possible frameworks to avoid additional military escalation.

Still, Rubio repeatedly emphasized Thursday that negotiations remain fragile and could ultimately collapse.

"We're dealing with a very difficult group of people," Rubio said. "It may not" happen

He added that Trump "has other options" if diplomacy fails, while stressing the president still prefers "the negotiated option and having a good deal."
