Trump's New White House Press Secretary Has a History of Conspiracy Claims, Including a Nazi Link to the Abortion Pill

Donald Trump's choice of Katie Zacharia as White House press secretary has brought renewed scrutiny of her past public statements, including a claim linking the abortion medication mifepristone to a company associated with Zyklon B, the poison used by the Nazis in the Holocaust.

In a November 2025 post on X, Zacharia wrote that mifepristone was 'connected to the manufacturer of the deadly gas Zyklon B, used in the World War II concentration camps.' She cited the historical relationship between German chemical company I.G. Farben and Degesch, which produced the pesticide used in Nazi killing operations.

The corporate history is real, but it does not establish that mifepristone contains Zyklon B or was developed by a Nazi-era company. A link between companies through later ownership is not evidence that their products share ingredients, origins or purposes.

Zacharia made a more direct comparison in a June 2025 online interview, saying abortion pills used 'the same chemicals' as those used in Nazi extermination camps. That assertion is not supported by the documented pharmacology of mifepristone.

What the Science and Timeline Show

Mifepristone was developed in France in the 1980s by pharmaceutical company Roussel-Uclaf, with French scientist Étienne-Émile Baulieu playing a central role. France approved the medicine in 1988. The US Food and Drug Administration (FDA) first approved Mifeprex, a mifepristone product, in September 2000.

The medicine works by blocking progesterone, a hormone needed to maintain pregnancy. It is commonly used with misoprostol in medication abortion. Neither medicine is Zyklon B, which released hydrogen cyanide when used as a poison gas.

The corporate timeline is also important. Hoechst AG acquired Roussel-Uclaf in 1997, years after France approved mifepristone. Hoechst was among the successor companies to I.G. Farben. That later corporate connection does not show that the drug was developed by I.G. Farben or that its formulation was derived from Zyklon B. The distinction matters: historical company ownership can be documented, but it cannot by itself prove a chemical or scientific claim about a medicine.

A Wider Record of Political Claims

The mifepristone statements are not the only comments drawing attention. In December 2025, Zacharia wrote that the 'price of a stolen 2020 election' was 'American Blood' while responding to a tribute to Army Specialist Sarah Beckstrom, a National Guard member who was fatally shot in Washington, DC. There is no evidence that widespread fraud changed the result of the 2020 presidential election. Beckstrom was deployed to Washington during Trump's presidency in 2025, and Zacharia presented no evidence connecting former President Joe Biden to her death.

Trump announced Zacharia's appointment on 9 October 2026. She previously served briefly as a Department of Homeland Security spokesperson and worked as a senior communications adviser for Trump Media & Technology Group. She has also appeared regularly as a conservative commentator on television.

The Stakes for the White House Briefing Room

The press secretary is one of the administration's most visible public communicators, responsible for answering reporters' questions and explaining White House policy. The role makes accuracy particularly consequential when public debate involves medicine, public health or disputed political events.

Reproductive Freedom for All, an abortion-rights advocacy organisation, criticised Zacharia's appointment. Its president and chief executive, Mini Timmaraju, said Trump was giving the anti-abortion disinformation movement a major platform. That is the organisation's political assessment, rather than an independent finding.

The central issue is not whether companies have complicated histories. It is whether those histories support the conclusions drawn from them. In this case, the documented development of mifepristone and its known mechanism do not substantiate claims that the medication uses chemicals from Nazi extermination camps.
