CHARLOTTE, N.C. (AP) — Some are arguing former CIA Director David Petraeus received preferential treatment in his sentence for providing classified information to his mistress, who was also his biographer.

Petraeus was sentenced Thursday to two years' probation and fined $100,000 on a federal misdemeanor count of unauthorized removal and retention of classified material.

Mark Zaid, a Washington attorney who regularly represents clients in national security cases, says the government showed a double standard.

Zaid contrasted the Petraeus case with that of his former client, ex-CIA officer John Kiriakou. In 2012, Kiriakou pleaded guilty to intentionally disclosing the identity of a covert agent to a reporter and was sentenced to 2 1/2 years in prison. Petraeus, then CIA director, hailed the conviction.
