The resignation of Director of National Intelligence Tulsi Gabbard adds a new layer of instability to a Trump administration already grappling with multiple high-level staff changes.

Tulsi Gabbard resigned as Director of National Intelligence on Friday, citing her husband’s battle with cancer, capping a contentious tenure that saw her frequently sidelined from President Trump’s core national security decisions. Her departure, effective June 30, marks the fourth cabinet-level exit in under three months and injects fresh uncertainty into the U.S. intelligence apparatus amid ongoing geopolitical tensions.
"I must step away from public service to be by his side and fully support him through this battle," Gabbard wrote in a letter to Trump, which she posted on social media. Trump, in a post on his Truth Social platform, said Gabbard had “done an incredible job” and announced her principal deputy, Aaron Lukas, would serve as acting director.
Gabbard’s exit follows those of Homeland Security Secretary Kristi Noem, Attorney General Pam Bondi, and Labor Secretary Lori Chavez-DeRemer since March. This rapid turnover of senior officials points to a pattern of instability within the administration, a factor that market participants are watching closely for its potential to disrupt policy and increase geopolitical risk.
The departure of the nation’s top intelligence official comes as the administration weighs further action against Iran and manages the fallout from military operations in Venezuela. Gabbard’s historically anti-interventionist stance often put her at odds with the administration's more hawkish members, and her exit removes a dissenting, though often marginalized, voice on foreign policy.
Gabbard’s year-and-a-half as DNI was marked by a consistent friction with the White House and the broader intelligence community. A former Democrat who endorsed Trump in 2024, she was a surprise pick to oversee the nation’s 18 spy agencies. Her political journey was built on opposing the foreign wars she was now expected to oversee intelligence for.
She was frequently kept out of the loop on major national security operations. Sources reported she was largely ignorant of the details surrounding the operation to snatch Venezuelan leader Nicolás Maduro and was not a significant part of the conversation before the U.S. and Israel began a war with Iran in February. Instead, Trump relied more heavily on CIA Director John Ratcliffe, a holdover from his first term.
The tension was most visible on the subject of Iran. In March, Gabbard’s prepared testimony to Congress stated that U.S. strikes had “obliterated” Iran’s nuclear program and that there had been “no efforts since then to try to rebuild.” This directly contradicted Trump’s public assertions of an imminent threat, leading to Gabbard not reading that portion aloud during the hearing. When pressed, she deferred to the president, stating, “It is not the intelligence community’s responsibility to determine what is and is not an imminent threat.”
While sidelined on foreign policy, Gabbard used her office to pursue some of Trump’s domestic political objectives. She was present when FBI agents raided an election center in Fulton County, Georgia, as part of the president’s effort to relitigate the 2020 election. The move drew criticism, as her office was created to focus on foreign, not domestic, matters.
Her departure adds another layer of uncertainty for markets. The constant churn in senior national security roles can be perceived as a risk, potentially leading to volatility in sectors sensitive to geopolitical events, such as defense and energy. The last time the administration saw a similar string of resignations, defense stocks saw a brief period of volatility as investors priced in the potential for erratic policy shifts. With Gabbard’s exit, the focus now turns to her replacement and whether the administration will seek a nominee who aligns more closely with its hawkish instincts.
