Were Clinton 'top secret' emails illegal? What history tells us about such cases
Hillary Clinton's home email server contained top-secret messages. But it's not uncommon for workers with access to classified material to mishandle it.
News that Hillary Clinton's home email server contained top-secret messages brings renewed attention to the security of her mail system and to the laws and regulations that control classified information.
The new disclosure, and the question of whether it exposes her to more serious legal problems, was certain to escalate political heat on the Democratic presidential candidate ahead of Monday's Iowa caucuses, the first contest on the 2016 nominating calendar.
FBI Director James Comey, whose agency is looking into the setup of the server, has said only that the investigation is being conducted without regard for politics. Officials have given no public hint as to when or how the probe will be finished.
Stephen Vladeck, an American University law professor and national security law expert, said it would be a stretch, based on what's now known, to think Clinton could be charged under any existing statute for her behavior.
"This is an area where the government tends not to test the margins too often," Vladeck said.
It's not uncommon for workers with access to classified material to mishandle it, and by far the bulk of those cases don't attract the attention of federal prosecutors.
But when the Justice Department does pursue a case, it often relies on a statute that bars the unlawful removal and retention of classified documents. That low-level charge, meant for cases in which defendants improperly hold onto information that they know to be classified, carries a fine and maximum yearlong prison sentence and is reserved for people who have "really, really screwed up," Vladeck said.
Much more serious is another statute that makes it illegal to knowingly disclose classified information to someone who's not authorized to receive it.
Each case that's resulted in prosecution has unique facts, making comparisons difficult. Investigators invariably take into account questions of knowledge, damage to national security, who sent, received or stored the information, and whether the material was classified at the time of transmission.
Some examples of past cases concerning classified information:
The best-known recent prosecution involves the former CIA director who pleaded guilty last year to a misdemeanor count of unlawful removal and retention of classified materials. He was spared prison as part of his plea and was given two years' probation by a judge who faulted him for a "serious lapse in judgment."
The retired four-star Army general admitted that he loaned his biographer, Paula Broadwell, with whom he was having an affair, eight binders containing highly classified information regarding war strategy, intelligence capabilities and identities of covert officers. Petraeus kept the binders in an unlocked desk drawer at his home, instead of a secure facility that's required for handling classified material.
There's a critical distinction.
While Clinton has repeatedly said she didn't send or receive anything that was classified at the time — something the State Department now says it's investigating — the Petraeus plea deal makes clear that he knew the information he provided was classified. He told Broadwell in a recording revealed by prosecutors that the binders had "code-word stuff in there."
When initially questioned by the FBI, he denied having given Broadwell classified information, but in his plea deal he avoided being charged with making a false statement.
The outcome drew accusations of a double standard for senior brass from defense lawyers who asserted that their less-influential clients wouldn't have been treated with such leniency.
Deutch was CIA director from May 1995 until December 1996. He came under Justice Department investigation after his resignation when classified material was found on his home computer in Maryland.
An internal CIA investigation found that he stored and processed hundreds of files of highly classified material on unprotected home computers that he and family members also used to connect to the Internet, making the information potentially vulnerable to hackers.
A report by the Defense Department inspector general found that Deutch had failed to follow "the most basic security precautions" and faulted him for rejecting Pentagon requests that security systems be installed on his home computers.
Deutch apologized for his actions and was pardoned by President Bill Clinton before the Justice Department could file a misdemeanor plea deal for mishandling government secrets.
Berger was the national security adviser during Bill Clinton's second term. After leaving office, he found himself in trouble for destroying classified documents.
Berger, who died in December at age 70, pleaded guilty in 2005 to illegally sneaking classified documents from the National Archives by stuffing papers in his suit. He later destroyed some of them in his office and lied about it. The materials related to terror threats in the United States during the 2000 millennium celebration.
He pleaded guilty to a misdemeanor count of unauthorized removal and retention of classified material, and though he avoided prison time, he lost access to classified material for three years.
A judge fined him $50,000, higher than the amount recommended by prosecutors.
He called his actions a lapse in judgment that came as he was preparing to testify before the Sept. 11 commission that examined the events leading up to the 2001 attacks.
"I let considerations of personal convenience override clear rules of handling classified materials," Berger said at the time.
Nishimura, a former Naval reservist in Afghanistan in 2007 and 2008 and a regional engineer for the U.S. military, was investigated for downloading and storing classified information on his personal electronic devices.
Prosecutors say he carried the materials with him off-base in Afghanistan and ultimately took classified Army records to his home in Folsom, California, after his deployment ended.
His lawyer, William Portanova, said his client never intended to break the law but was a "pack rat" who thought nothing of warehousing Army records at home alongside personal belongings.
FBI agents who searched his home in 2012 found classified and unclassified military records, both in hard copy and digital form, and Nishimura admitted to the government that he had destroyed some of the information.
Nishimura pleaded guilty in July to unauthorized removal and retention of classified materials. A judge fined him $7,500, and he was ordered to surrender his security clearance.
The violation was a technical and unintentional one, Portanova said, but one that the Justice Department nonetheless thought it needed to punish "to make its point."
