Nancy Mace Insists ‘Congress Should Have a Say’ on Ground Troops in Iran

Representative Nancy Mace, a South Carolina Republican, sharpened her opposition to any deployment of U.S. ground troops in Iran, saying on Sunday that Congress must be consulted before American forces are sent into what she describes as a full‑scale ground war.

“If we’re going to do a conventional ground operation with Marines and 82nd Airborne, that is a ground war that I believe Congress should have a say and we should be briefed,” Mace said while appearing on CNN.

“We don’t want troops on the ground.” Her remarks come amid growing signs that the Trump administration is at least preparing for the possibility of limited ground operations, even as the White House insists no decision has been made to put American troops on Iranian soil. Why It Matters The congresswoman's comments reflect a broader unease within parts of the Republican base about the direction of the Iran war, particularly as the conflict stretches beyond initial airstrikes and into discussions of ground combat.

At the Conservative Political Action Conference (CPAC) last week in Texas, several younger Republican attendees said the war has shaken their support for President Donald Trump, who campaigned on avoiding new foreign entanglements. Some attendees described the conflict as a betrayal of Trump’s “America First” promises, saying they did not vote for a president who would risk another prolonged Middle East war. Those sentiments contrast with the official messaging from the administration, which has emphasized military success in Iran and insisted that escalation can be controlled.

But for lawmakers like Mace, who backed U.S. and Israeli airstrikes against Iran, the growing disconnect between campaign rhetoric and battlefield realities raises political and constitutional concerns—especially if ground forces are ultimately ordered into combat. What to Know Mace’s stance has developed over several days, becoming more explicit after she received classified briefings on the conflict. On March 25, she spoke to reporters outside the U.S. Capitol after a House Armed Services Committee briefing.

At that point, she vowed to oppose any funding that would enable “boots on the ground” in Iran, warning against repeating the mistakes of Iraq and Afghanistan. Her focus was on preventing escalation rather than on the mechanics of congressional authorization. The following day, she appeared on a CNN Politics segment after another classified briefing she described as “frustrating.”

During that interview, she said Congress “needs to have a greater say” if U.S. troops are deployed, signaling a shift toward a clearer war‑powers argument. By Sunday, Mace refined the point further during a longer CNN interview. She drew a sharp distinction between positioning forces in the region and ordering them into Iran for ground combat, saying the latter would amount to a ground war requiring congressional involvement.

“I think that’s a line for a lot of people," the congresswoman said on Sunday. ”

If we’re going to do that, then come to Congress and get the proper authorities to do so.” Her position echoes concerns voiced by some CPAC attendees, particularly younger conservatives who said talk of ground troops was a red line. Several warned that sending U.S. forces into Iran would fracture Trump’s coalition ahead of the midterms this year, with some saying they already feel disillusioned by the war.

Meanwhile, Trump has sent mixed signals about ground forces. He has said that troops may not be necessary, while declining to rule them out entirely, arguing it would be unwise to telegraph military intentions. Defense officials have echoed that ambiguity, saying all options remain available even as they stress the effectiveness of air and naval operations so far.

What People Are Saying President Donald Trump to the New York Post earlier this month: “I don’t have the yips with respect to boots on the ground—like every president says, ‘There will be no boots on the ground.’ I don’t say it. I say, ‘probably don’t need them,’ [or] ‘if they were necessary.’”

Mohammad-Bagher Ghalibaf, speaker of Iran’s Parliament, on Sunday in state media: “The enemy publicly sends messages of negotiation and dialogue, but secretly is planning a ground attack. The U.S. is unaware that our men are waiting for the arrival of American troops on the ground to set them on fire and punish their regional partners forever. Our firing continues.

Our missiles are in place. Our determination and faith have increased.” Former GOP Representative Matt Gaetz at CPAC on Friday: “A ground invasion of Iran will make our country poorer and less safe.

It will mean higher gas prices, higher food prices, and I’m not sure we’d end up killing more terrorists than we would create.” Senator James Lankford, an Oklahoma Republican, on NBC News’ Meet the Press on Sunday when asked about troops on the ground in Iran: "

To be very clear on this, the worst thing that can happen is to be able to have this kind of conflict start and to not end it, to leave it undone. We've got to be able to finish this…If this is special forces to be able to carry out a specific operation—get in, get out—-that's very different than longstanding occupation.” What Happens Next For now, the White House maintains that no decision has been made to deploy U.S. ground troops into Iran, describing Pentagon planning as routine contingency work rather than a signal of intent.

But as U.S. forces continue to build up in the region and Iran issues threats against American troops, lawmakers like Mace—and skeptics within Trump’s own base—are likely to keep pressing for clearer limits on how far the war can go.
