Harvard researcher detained in February for failing to declare frog embryo samples says she didn’t lie to government

A Harvard Medical School researcher currently detained by Immigration and Customs Enforcement says she should have reviewed customs protocols before attempting to enter the US with “non-hazardous” frog embryo samples but insists what she told immigration agents was misunderstood.

“I never provided false information to any government official,” Kseniia Petrova, a Russian national, said in a statement issued Thursday. “Some of my words were misunderstood and inaccurately reflected in the statement that the officer presented for my signature.”
