Olshansky and Lindorff include as rationales for impeachment in The Case for Impeachment

Olshansky was the recipient of a document leaked by Lieutenant Commander Matthew Diaz, that later lead to his court martial, detention, and discharge.The efforts of the Center for Constitutional Rights were impaired by the Bush administration's policy of withholding the captives' identities. Diaz had met Olshansky during a visit to Guantanamo, and he sent her a list in an unmarked greeting card. The list provided by Diaz contained the names of 550 captives.

Olshansky suspected the list might have been classified, so she contacted Federal authorities.

After leaving the Center for Constitutional Rights Olshansky was hired as director of the International Justice Network.

In 2007 Olshanksy was appointed the Leah Kaplan Visiting Professor in Human Rights at Stanford University's Law School.
