Senate Republicans Question Pentagon Leadership of Secretary Pete Hegseth

4/29/2026, 12:15:29 AM

Rising Concerns Over Pentagon Management

A growing bloc of Senate Republicans has expressed waning confidence in Defense Secretary Pete Hegseth’s ability to steer the Department of Defense. Their unease centers on a series of senior-level departures—including Army Chief of Staff Gen. Randy George and Navy Secretary John Phelan—followed by reports that Hegseth has also dismissed Chairman of the Joint Chiefs Gen. C.Q. Brown, Chief of Naval Operations Adm. Lisa Franchetti, Defense Intelligence Agency director Lt. Gen. Jeffrey Kruse and Air Force Chief of Staff Gen. James Slife. Lawmakers say the turnover “hollowing out” experienced leadership and threatens stability as the United States remains engaged in the war with Iran. Hegseth is slated to testify before the House Armed Services Committee on Wednesday and the Senate Armed Services Committee on Thursday to defend the department’s $1.5 trillion budget request.

Background and Recent Personnel Changes

Hegseth, an infantry officer from the Minnesota Army National Guard, was confirmed as secretary last year with pivotal support from Republican senators, including Thom Tillis. Critics now point to his limited managerial experience—he previously oversaw “30 or 40 people”—as inadequate for a bureaucracy of roughly 1.3 million civilian and uniformed personnel. The Pentagon’s own spokesperson, Sean Parnell, noted that reforming the department “without changing senior military leadership” is “extremely difficult,” but declined to comment on the specifics of each departure.

Key Players

Pete Hegseth – Secretary of Defense.

Gen. Randy George – Former Army Chief of Staff (dismissed April 2024).

John Phelan – Former Navy Secretary (fired May 2024).

Dan Driscoll – Army Secretary (in a reported feud with Hegseth).

Michael Obadal – Under Secretary of the Army (absent during George’s ouster).

Sen. Thom Tillis (R-N.C.), Sen. Joni Ernst (R-Iowa), Sen. Lisa Murkowski (R-Alaska), Sen. Roger Wicker (R-Miss.), Sen. Mike Rounds (R-S.D.) – Republican senators voicing criticism.

Sean Parnell – Pentagon spokesperson.

President Donald Trump – Holds ultimate authority over the secretary’s tenure.

Timeline of Recent Developments

Early April 2024 – Gen. Randy George asked to resign.

Mid-May 2024 – Navy Secretary John Phelan dismissed.

Late May 2024 – Hegseth testifies before House Armed Services Committee.

Early June 2024 – Scheduled Senate Armed Services Committee hearing; Senate Republicans signal desire for new leadership.

Data and Organizational Scope

Hegseth’s prior management experience: “30 or 40 people.”

Department of Defense budget request: $1.5 trillion.

Senior officials removed under Hegseth: at least six high-ranking officers (Brown, Franchetti, Kruse, Slife, George, Phelan).

Official Statements and Responses

Pentagon spokesperson Sean Parnell emphasized that the secretary “does not comment on the nature of [senior officers’] departure” but affirmed the administration’s right to appoint officers who “fully and expeditiously embrace the priorities, policies, and objectives of this Administration.” He added that “necessary changes have been made and will continue to be made” as the department undergoes reform. Hegseth is expected to use his upcoming committee appearances to justify the budget and address concerns about personnel turnover.

Criticism and Opposition

Republican senators argue that Hegseth’s personnel decisions reflect a “lack of experience” and “missing the mark on personnel.” They also question his judgment on health policy, noting the recent decision to drop the mandatory flu-shot requirement for service members. While some GOP members commend recent combat successes against Iran, the prevailing sentiment among the dissenting senators is that the current leadership turbulence undermines the Pentagon’s effectiveness.

Conflicting Reports and Gaps

Sources do not disclose the specific reasons behind Gen. George’s resignation or John Phelan’s termination, nor do they provide Hegseth’s own commentary on the departures. The extent to which the reported feuds with Dan Driscoll and Michael Obadal influence decision-making remains unclear.

“there’s no question he’s got a failing grade” on technical, managerial skills. — Sen. Thom Tillis (R-N.C.)

Republican leaders have indicated they may urge President Trump to consider a new secretary if confidence does not improve, while the administration prepares to defend the $1.5 trillion defense budget before Congress.
