A Republican member on the House Armed Services Committee told Fox News Digital ahead of the midterm elections that the Trump administration has a key decision to make on the future of the U.S.-Iran war as "continuing to do just enough not to lose, but not enough to win, is not OK."

Rep. Pat Harrigan, R-N.C., made the comments as Vice President JD Vance declared during a Fox News town hall on Thursday that he promises "Donald Trump is not going to let Iran become a forever war." Official and military sources also told Fox News this week that movements are being made in the Middle East to give the president options if he decides to resume strikes against Iran.

"I share my constituents and many Americans' perspective that I'm very, very frustrated that this war is not over. The way that ultimately this administration went about conducting the war, it needed to execute it and wrap it up in a very short period of time, and we are not there yet," said Harrigan, who is running for re-election in North Carolina's 10th Congressional District.

"That being said, Iran can't have a nuclear weapon. And so at the end of the day, I do believe that this was a war that was inevitable at some point, but the party that's in power and the administration that decided to pull the trigger on it is responsible for the outcome, and they're responsible for the outcome in a very short period of time. Otherwise, things get really, really difficult," Harrigan continued. "And I think we've been seeing that, both from a political perspective but also from a policy perspective."

"And so while the administration needs to wrap this up, we are not in a forever war, but we need to make sure that we're not... we keep the mission the same. We accomplish the mission. And we do what it takes to either win or come home," Harrigan added. "And that binary decision has to get made by this administration."

Harrigan told Fox News Digital that Trump "needs to involve Congress" if he chooses to renew military action against the Iranian regime.

"I think that that will long-term set the course for the country to be resolute in affirming and actually executing and accomplishing the objectives that exist. Because look, like it or not, Congress is responsible for the funding arm of the government. And if they run out of money to accomplish the objectives, then that is not good for our strategic interests," he said. "So, in my opinion, Congress and the White House need to be very closely involved in making the next set of decisions that exist for this conflict."

"And we do need to make sure, again, that we either do what it takes to actually win in Iran, or we need to take the three out of five objectives that we've accomplished and say that, you know what? We've largely accomplished our strategic objectives. We've got more work to do over the long-term that's going to require consistent and persistent over the horizon monitoring of their nuclear program. And we're going to have to mow the lawn every now and again, and everybody's got to realize that, and leave, right?" Harrigan continued, mentioning how the U.S. has prevented Iran from obtaining a nuclear weapon and eliminated Tehran's missile and drone production.

"But we've got to choose one of those two options because continuing to do just enough not to lose, but not enough to win, is not OK," he said. "It's not OK for the American people, it's not OK for our troops, it's not OK for geopolitical and economic stability. And it does not serve the long-term strategic interests of the United States. So it's time to choose."

Harrigan, a Green Beret and business entrepreneur, is running for re-election on Tuesday in North Carolina. He is facing off against Democrat challenger Ashley Bell, a physician associate, and Libertarian candidate Steve Feldman, who ran unsuccessfully for the seat two years ago.

As a current member of Congress, Harrigan told Fox News there is "no question" the Republican Party's House majority is at stake heading into Election Day.

"Whoever has 218 votes gets to chart the course of the direction of the House, the work that its committees do. And in particular, as it relates to the Trump administration, whether or not President Trump's going to get impeached," he added.

"What this boils down to is the future direction of the country. Are we going to be stuck looking backwards instead of actually looking forwards, dealing with the actual business of the country and the free world, or are we going to be stuck in some sort of a Democratically-led nightmare that is simply going to be obstructionist to the conservative principles and values that people voted for in 2024?" Harrigan asked. "That's what's on the line this election cycle."

War Secretary Pete Hegseth fired one of the Pentagon’s senior strategic planners amid an investigation into allegations he leaked classified information to journalists about the Iran war, Russia’s war in Ukraine and other sensitive matters, a Department of War official told Fox News.

The official said Lt. Gen. Brett Sylvia failed three polygraph examinations related to alleged disclosures of classified information. The investigation has been referred to the Justice Department. 

Sylvia is also accused of meeting journalists outside the Pentagon with the alleged intention of leaking classified material after Hegseth imposed new media restrictions requiring reporters to be escorted inside the building.

HEGSETH ANNOUNCES JOINT TASK FORCE WITH DOJ TO PROSECUTE LEAKS TO JOURNALISTS 'WITH THE FULL FORCE OF THE LAW'

Fox News Digital has reached out to the DOJ and Sylvia for comment but did not hear back at time of publication. 

Sylvia served as director of the Joint Staff’s Directorate for Strategy, Plans and Policy, known as the J5, a senior role responsible for developing military strategy and advising the chairman of the Joint Chiefs. The J5 has been sidelined from that role since the spring, according to well-placed sources who spoke to Fox News.

The official stressed that Sylvia was not a central planner of the Iran war, which falls under U.S. Central Command and its commander, Adm. Brad Cooper.

The Atlantic first reported Sylvia’s ouster Wednesday night, citing sources who said Hegseth had lost confidence in the three-star general amid tensions with Pentagon policy chief Elbridge Colby.

Sylvia is the second officer leading the J5 to be removed under Hegseth, following Lt. Gen. John McGee. Hegseth also removed Lt. Gen. Douglas Sims, then director of the Joint Staff, earlier this year.

The abrupt removal comes as the Pentagon reportedly weighs renewed military action against Iran.

U.S. officials have reportedly warned allies in the Middle East to prepare for possible renewed strikes after next week’s midterm elections and potential Iranian retaliation, while additional U.S. forces are moving into the region.

A 1994 West Point graduate, Sylvia has served more than three decades in the Army, including multiple deployments to Iraq and Afghanistan, and was wounded in combat. Before taking over the J5 in December, he commanded the 101st Airborne Division at Fort Campbell and had previously served as the J5’s vice director.

Sylvia’s removal is the latest in a broader turnover of senior military leadership under Hegseth, with nearly two dozen generals, admirals and other senior leaders fired, pushed out or otherwise departing during his tenure.
