U.S. Rep. Robert Garcia (D-Calif.), ranking member of the House Oversight Committee, sent a letter on Thursday to U.S. Health Secretary Robert F. Kennedy Jr. demanding answers about the Trump-Vance administration’s “systematic” elimination of programs to fight HIV in the U.S. and around the world.

Also signed by Democratic Congressman Raja Krishnamoorthi of Illinois, the letter requests information about cuts to federal support for HIV research, including vaccine development efforts, the shuttering of the HIV prevention division of the Centers for Disease Control and Prevention, and the defunding of programs providing HIV treatment and prevention services since President Donald Trump returned to the White House.

The lawmakers requested responses by or before the end of July.

“It is shameful that HHS Secretary RFK Jr. and the Trump Administration are working to dismantle our HIV research, care, and prevention programs aimed at eradicating the disease across the world,” Garcia said. “This decision is absolutely reckless and puts millions of lives at risk.  Oversight Democrats refuse to let Secretary Kennedy’s reliance on conspiracy theories and misinformation threaten the health and safety of our public health.” 

“The Trump Administration’s reckless decision to gut HIV prevention and research programs is not only scientifically indefensible—it’s morally unconscionable. These cuts jeopardize the health of millions, both at home and abroad, and reverse decades of bipartisan progress in the fight against HIV/AIDS,” Krishnamoorthi said. “We’re demanding answers because the American people, and the global community, deserve better than politically motivated neglect of public health.”

Echoing warnings from HIV and public health experts, the congressmen in their letter stressed that backsliding in efforts to fight the disease at home and abroad come just as advancements in treatment and prevention have finally put some of the most ambitious goals to end the epidemic within reach.

The letter suggests that Kennedy’s embrace of misinformation about HIV might explain, to some extent, his dismantling of programs to end the epidemic at home and abroad, specifically, pointing to the secretary’s history of challenging the overwhelming and longstanding scientific and medical consensus about the causal relationship between HIV and AIDS.

The congressmen also detailed many of the real-world consequences of health policy concerning HIV in Trump’s second term. For example, they note experts anticipate there will be millions of excess new HIV infections and hundreds of thousands of excess HIV-related deaths in Sub-Saharan Africa in just one year.

The letter also warns that “President Trump’s Fiscal Year 2026 budget request for domestic HIV program calls for a $1.5 billion reduction in funding,” which “could lead to more than 143,000 additional HIV cases in the United States within five years and about 127,000 additional deaths from HIV and AIDS-related causes.”

Garcia’s leadership of Oversight Dems will be closely watched

If Democrats recapture a majority of seats in the House next year, Garcia becomes chair of the committee and has access to far more powerful tools to exercise oversight — like the authority to issue subpoenas (unilaterally or by majority vote) compelling witnesses to testify or requiring officials to turn over documents.

Leadership positions, especially coveted spots leading the most powerful committees in Congress, are typically awarded based on seniority. When the House Democratic caucus elected Garcia on June 24, it marked the first first time in more than a century that a second-term member was selected for the role.

During his brief time in Washington, the congressman, who is openly gay and formerly served as mayor of Long Beach, has emerged as arguably one of the strongest communicators in the House Democratic caucus and one of his party’s most vocal critics of the second Trump administration.

Thursday’s letter, which comes less than a month after his election as ranking member, may signal how Garcia will approach fact finding missions and investigations, or where he will focus the committee’s work, under the vastly expanded powers that might be available to him after the midterms.
