WASHINGTON, DC: Sen Mitch McConnell warned that President Donald Trump’s defense agenda could be derailed by its own funding structure, exposing a rare Republican divide over national security spending.

The Kentucky Republican challenged the administration’s budget approach during a Senate hearing. His criticism carried added weight because Republicans control Washington and are trying to advance Trump’s defense priorities.

Mitch McConnell warns Trump defense plan at risk

Speaking at a Senate Defense Appropriations Subcommittee hearing, McConnell said the administration’s budget request was structured in a way that “would put consistent funding for key priorities at unnecessary risk.”

The longtime senator, who chairs the subcommittee, pointed to what he described as “core pieces of the president’s defense agenda” being requested through one-time reconciliation spending rather than full-year appropriations.

According to McConnell, those items include “multi-year procurement contracts for critical munitions, half of the F-35 program, Golden Dome, and drone dominance initiatives.”

“This is especially mystifying for multiyear procurement contracts,” McConnell said. “I mean, the need to budget for them annually is right there in the name.”

He argued that the administration’s approach created vulnerabilities for projects that Trump has identified as major defense priorities.

F-35 funding dispute sparks GOP concerns

McConnell escalated his criticism by warning that the administration’s broader strategy could backfire if partisan legislation stalls.

“The Administration’s choice to structure an ambitious $1.5 trillion dollar request in this way is yet another missed opportunity to put key aspects of our common defense on a stronger and more enduring fiscal footing,” he said.

Calling the issue more than a technical budget dispute, McConnell added that the strategy was “a recipe for major disruptions in the very possible event that party-line reconciliation fails.”

He reserved some of his sharpest criticism for funding tied to the F-35 program.

The Pentagon, McConnell said, “will continue to step on its own tail if it insists in housing procurement of new airframes primarily in one-off reconciliation spending.”

He described the F-35 as critical to both US operational readiness and support for key allies, adding that “there’s really no excuse for not placing it squarely in full-year appropriations.”

Mitch McConnell questions Pentagon’s battlefield readiness

McConnell also used the hearing to question whether defense leaders are adapting quickly enough to modern conflicts.

Addressing Air Force Secretary Troy Meink, Air Force Chief of Staff Gen Kenneth Wilsbach, and Space Force Chief of Operations Gen Chance Saltzman, he said he wanted answers about the “longer-term scaling” of key defense systems.

“At a fundamental level, I’m curious to hear from each of you about how the Department of the Air Force is applying the lessons of the modern battlefield,” McConnell said.

He added, “I’m concerned that the Pentagon as a whole is not learning quickly enough from the battlefields in Ukraine and the Gulf.”

McConnell warned that failures to adapt, particularly on force protection and counter-drone technology, carry “real and measurable costs.”

He closed by arguing that additional funding would be needed to cover operational expenses tied to Trump’s conflict with Iran and address longstanding munitions shortfalls, setting up further scrutiny of the administration’s defense spending plans in future budget battles.
