Following his admission that he leaked classified information to his mistress, Paula Broadwell, former CIA Director David Petraeus was fined $100,000 on Thursday by the court.

He was also sentenced to two years probation. Jill Westmoreland Rose, acting U.S. attorney for the Western District of North Carolina, said that the retired general lied to the FBI and CIA about removing and obtaining classified information.

Judge David Keesler increased the fine to $100,000 from the $40,000 recommended by prosecutors to discourage others from following what the decorated war hero and ex-four-star military man did.

Broadwell, aside from being the former general's mistress, is also his biographer. She is an Army Reserve officer.

Petraeus served in the military for 37 years, capped by his commanding the U.S. forces in Iraq and Afghanistan. After this, he was appointed as CIA director, but he was just more than one year in the job. He resigned in November 2012.

Petraeus said, "As I did in the past I apologize to those closest to me and many others including those that I was privileged to serve in government and in the military over the years," quotes ABC.

He thanked those who supported him and said he looks forward to the next phase of his life as a private citizen. Petraeus chairs the KKR Global Institute, an economic and geopolitical think tank owned by private equity company Kohlberg Kravis Roberts.

Petraeus avoided going to prison by entering into a plea deal to a misdemeanor charge of unauthorized removal and retention of classified material, which Keesler said was a lapse of judgment on the general's part, reports Reuters.

Several groups, however, questioned his plea deal for being a slap on the wrist and an indicator of a double standard by prosecutors.

The judge disclosed that high-ranking American military offices, legislators and even heads of states wrote letters that were submitted by lawyers of Petraeus to support the former CIA director. But they all agreed that the general "committed a grave but very uncharacteristic error in judgment."

Keesler added that what Petraeus did contrasted with his almost 40 years of dedicated public service.
