Quick Summary

US prosecutors are set to drop criminal charges against Kseniia Petrova, a Russian-born scientist at Harvard University, who was accused of smuggling frog embryos into the United States in February 2025. Prosecutors filed to dismiss the case after a federal judge ruled that Petrova could obtain evidence supporting her claim that she faced vindictive prosecution by the Trump administration. Federal prosecutors maintained they viewed Petrova’s claims as meritless but decided continuing with the prosecution would not serve substantial federal interests.

Story summary

On November 4, 2026, federal prosecutors moved to drop all criminal charges against Kseniia Petrova, a Russian-born scientist at Harvard University who had been accused of smuggling frog embryos into the United States since February 2025. The case was dismissed after a federal judge in Boston granted her access to evidence supporting her claims that she was being vindictively prosecuted by the Trump administration, which she argued targeted researchers and universities like Harvard as part of a broader political campaign. Petrova had been conducting cancer research at Harvard Medical School when customs officials detained her upon her return from France with undeclared frog embryo samples for research purposes. Prosecutors acknowledged that while they viewed her claims as "meritless," continuing the prosecution would divert significant time and resources from more substantial federal interests, leading to the dismissal of charges including smuggling goods into the United States, concealment of a material fact, and making false statements.
