Defense Secretary Pete Hegseth's campaign-style tour through early presidential primary states has anonymous officials telling the Washington Post he may be eyeing a 2028 White House bid, a move that would put him on a collision course with Vice President JD Vance.

Hegseth, 46, flew to Des Moines on military aircraft Monday to stump for GOP Rep. Zach Nunn at the Iowa State Fair, a venue where presidential hopefuls have tested their appeal for decades. The Pentagon justified the flight as necessary "due to the continuous need for secure communications and responsive transportation for national security," but the trip itself was described by a Pentagon spokesperson as occurring "in his personal capacity." The Daily Beast reported that officials familiar with Hegseth's thinking believe the defense secretary has his sights set on the presidency.

Iowa was not a one-off. The week before, Hegseth campaigned for Sen. Darline Graham in South Carolina, an early presidential primary state. And in May, he appeared for congressional candidate Ed Gallrein in Kentucky, backing Gallrein's successful primary challenge against incumbent Rep. Thomas Massie. Three states, three campaign swings, all while running the largest department in the federal government during an active military conflict.

A sitting defense secretary on the campaign trail is almost unheard of

CBS News noted that it is rare for any sitting defense secretary to campaign for candidates. The position has traditionally been treated as above partisan politics, a norm rooted in the idea that the person commanding the world's most powerful military should not be working the rope line at state fairs. Hegseth's travel schedule suggests he sees the job differently.

Nunn posted images on X of Hegseth showing off his tattoos at the Iowa event, a moment that underscored the former Fox News host's brand of populist showmanship. For a defense secretary managing a conflict abroad and rolling out new Pentagon initiatives at home, the optics leaned more toward retail politics than national security.

The 2028 speculation matters because President Trump has spent much of the year batting away questions about his successor. He has been described as pitting Vice President Vance against Secretary of State Marco Rubio for his blessing as heir to the movement he built. Vance, who enjoys backing from some of MAGA's wealthiest and most influential supporters, would be the presumptive frontrunner in any open Republican primary. A Hegseth bid would fracture that lane.

Trump himself has at times suggested he might pursue a third term, a scenario that would require amending the Constitution. That talk has kept the succession question murky, and may have given Hegseth room to maneuver without drawing an immediate rebuke from the White House.

Hegseth's tenure has been defined by bold moves and persistent controversy

Hegseth has governed the Pentagon like a man with something to prove. He conducted repeated purges of senior military officers and personnel he labeled "DEI hires." He announced plans for free hormone therapy for service members with low testosterone. He moved to formally censure Democratic Rep. Mark Kelly. And he evicted or censored mainstream defense and national security correspondents from the Pentagon press corps.

Those actions earned him loyalty from parts of the conservative base that view the defense establishment as captured by progressive ideology. But they also generated friction. Rep. Lauren Boebert has spoken publicly about frustrations with Hegseth's handling of congressional relationships, and Democrats have openly discussed impeachment as a midterm priority if they retake the House.

The so-called "Signalgate" episode remains the most damaging chapter of his tenure. Less than two months after the Senate confirmed him, Hegseth shared sensitive details of military strikes against Iranian proxies in Yemen through a Signal group chat that included 19 top administration officials, among them Vance, White House Chief of Staff Susie Wiles, and Deputy Chief of Staff Stephen Miller. Signal is not generally authorized for official government communications. The breach became public after Jeffrey Goldberg, editor-in-chief of The Atlantic, was accidentally added to the chat.

Hegseth's Senate confirmation itself was contentious. Allegations of assault, sexism, and links to far-right extremist ideology surfaced during his hearing. A November 2024 report by The New Yorker revealed that Hegseth had been removed from his post at Concerned Veterans for America in part over appearing repeatedly drunk on the job. NBC News reported that former Fox News colleagues had seen him drink before going on air. Hegseth promised senators at his confirmation hearing that he would not touch alcohol while serving as secretary.

An unpopular conflict and a 35 percent approval rating form a shaky launchpad

Any presidential ambition would have to contend with numbers that do not flatter the defense secretary. A CNN poll fielded in late July found that just 28 percent of voters approve of the war with Iran, a conflict the president promised would last only "a few weeks" but which has now stretched to nearly six months. An earlier CNN survey, from April, pegged Hegseth's own job approval at 35 percent.

The conflict has produced its own controversies. Reports described conditions aboard the USS Abraham Lincoln, deployed for more than 260 days, over 200 of them without a port call, including moldy showers, broken toilets, contaminated water, and food rations for a crew of 5,000 sailors and Marines. Hegseth dismissed those accounts as "completely misrepresented." When pressed about whether families of service members were worried, he answered flatly: "No, they're not."

Separately, Hegseth allegedly issued what were described as "kill-them-all" orders during military strikes on suspected narcotrafficking boats in the Caribbean, orders that unnamed legal experts characterized as potential crimes against humanity. A U.S. airstrike on an Iranian school reportedly killed 165 civilians, described as including dozens of children. The sourcing for both claims remains thin, with no named officials or documents cited publicly.

Hegseth has also reversed course on major policy decisions, including planned European troop reductions, adding to the impression of a Pentagon chief still finding his footing on the global stage.

Vance stands as the clearest obstacle to a Hegseth primary bid

If Hegseth does run, the Republican primary would pit two very different brands of populist conservatism against each other. Vance carries the institutional weight of the vice presidency and the financial backing of the MAGA donor class. Hegseth carries a Fox News following, a combat veteran's biography, and a willingness to pick fights that more cautious politicians avoid.

Democrats, meanwhile, have their own plans for Hegseth. Rep. Jake Auchincloss has said that impeaching the defense secretary would top the agenda if his party wins the midterms. That threat, combined with low approval numbers and an unpopular war, makes Hegseth's political calculus unusually risky.

Hegseth has not confirmed any presidential ambition. The speculation rests on anonymous officials and a travel schedule that looks more like a candidate's itinerary than a defense secretary's. The Pentagon insists the Iowa trip was personal. The military aircraft says otherwise.

A cabinet secretary who campaigns through Iowa, South Carolina, and Kentucky while managing an active conflict is not building goodwill for his department, he is building a brand. Whether that brand survives the weight of a 35 percent approval rating and a war most Americans oppose is a question Hegseth has not yet had to answer out loud.
