De Sousa, a naturalized American from India, was arrested in Portugal last October and earlier this month lost her latest court bid to halt her extradition to Italy. She faces four years in prison there over her alleged role in the rendition of a suspected terrorist 13 years ago.

De Sousa has launched numerous unsuccessful bids over the years to clear her name, but has received little known help from the government she served for more than a decade.

If she’s sent to prison, she would become the first CIA officer and U.S. diplomat imprisoned over the controversial rendition program.
