The Facts

  • Kseniia Petrova, a 31-year-old Russian researcher at Harvard Medical School, was charged on Wednesday with smuggling goods into the United States after TSA officials discovered clawed frog embryos and embryonic samples in her luggage in February at Boston's Logan Airport.
  • Petrova, who has been held at a U.S. Immigration and Customs Enforcement (ICE) detention facility in Louisiana since February, faces up to 20 years in prison and a $250,000 fine if convicted of the smuggling charge.
  • Federal prosecutors allege that text messages on Petrova's phone indicate she knew a permit was required for the biological materials, with one message showing her response: "No plan yet. I won't be able to swallow them" when asked about getting samples through customs.

The Spin


Pro-establishment narrative

These charges are necessary to show the U.S. government is serious about protecting its borders. Petrova, a native of Russia, knowingly attempted to circumvent customs requirements before she was caught at the airport. Her text messages and false statements made to federal officers about the contents of her luggage prove the government is correct to be extra careful about letting her return stateside.

Establishment-critical narrative

The government's actions represent a calculated effort to criminalize a minor customs violation and punish a respected scientist working on crucial cancer and aging research for not being born in America. This case and others show the Trump administration is determined to chill international scientific collaboration and misuse power to terrorize noncitizen academics for unknown reasons.
