The aide, Samantha Deforest Davis, was a staff assistant in Hassan’s office from August 2017 until last December. She was fired after Capitol Police discovered her possible involvement in the so-called “doxing” effort.

Court documents accuse Davis of aiding 27-year-old Jackson A. Cosko, a former Hassan aide who has pleaded guilty to five federal offenses, including two counts of making public restricted personal information, and one count each of computer fraud, witness tampering and obstruction of justice.

Prosecutors alleged Wednesday that Davis was persuaded by Cosko to “wipe down” Senate computers he had hacked. Davis now faces two misdemeanor charges: one federal count of aiding and abetting computer fraud and a District count of attempted evidence tampering, the Washington Post reported.
