Committee of Concerned ScientistsInstitutional position in a public letter signed by the Committee’s co-chairs

“The United States does not recognize inherited political guilt.”
Official statement

Where this statement fits
Did ICE Detain an Entire Family for What Eissa Hashemi’s Mother Did?
On April 11, 2026, the U.S. State Department said it had terminated the lawful permanent resident status of Seyed Eissa Hashemi, Maryam Tahmasebi, and their son, and that ICE had them in custody pending removal. Officials cited family ties and foreign-policy or national-security grounds; the family, its lawyers, and other commentators have disputed the action as family-based punishment. This case records those competing positions without deciding the legal validity of the action or the family’s current status.
