WASHINGTON (AP) -- A fight between the Senate and the CIA over whether crimes were committed in the handling of sensitive classified material appears unlikely to be resolved in the courts, legal experts say.
The simmering dispute erupted in public this week when Sen. Dianne Feinstein, D-Calif., accused the CIA of improperly searching and removing documents from a computer network used by Senate investigators to compile a report on the George W. Bush-era interrogation program for suspected terrorists. CIA Director John Brennan has denied that the CIA hacked into the computers but says an audit was necessary to determine whether Senate staffers had improperly obtained sensitive CIA documents.
The matter has landed in the lap of the Justice Department, which has been asked to investigate whether laws were broken.
But legal experts say prosecutors will likely be hesitant to wade into a separation-of-powers dispute between two branches of government that involves a muddled area of the law and raises as many policy questions as it does legal ones. The Justice Department receives far more requests to open criminal probes than it chooses to pursue. Federal courts, too, are reluctant to referee power disputes between the two other branches of government.
"There's an ongoing debate about what the proper role of each of these branches of government is," said Jennifer Granick, director of civil liberties at the Stanford Center for Internet and Society. "Who's watching the watchers? Is Congress watching the CIA or is the CIA watching Congress? And who's in control here?"
If prosecutors were to get involved, they would confront murky legal questions. Any inquiry would turn on highly specific facts, which are still in dispute, about whatever agreement on computer access existed between the CIA and the Senate Intelligence Committee, whose staff has produced a 6,300-page classified report about waterboarding and other harsh methods used to interrogate suspected terrorists in overseas prisons. Neither the full report nor a shorter summary has been released to the public.
At the committee's request, the CIA provided 6.2 million pages of material on CIA-provided computers and allowed them to be reviewed under strict ground rules at a secure site in northern Virginia. But Senate investigators noticed that documents they once had been able to access had vanished from the computers, and Feinstein accused the CIA of interfering in the committee's investigation. Brennan denied the allegations, but said an audit was needed to determine if there was a computer system security breach.
In her floor speech, Feinstein cited possible violations of the Constitution's Fourth Amendment, which bars unlawful searches and seizures, as well as a presidential executive order prohibiting the CIA from conducting domestic spying. She also singled out the Computer Fraud and Abuse Act, an often-used but contentious statute that makes it a crime to use a computer without, or in excess of, authority. Legal experts say it's not clear that the statute would apply here.
"This is a disagreement among the branches at a high level, but I doubt that there's going to be criminal charges," said Orin Kerr, a George Washington University law professor and former computer crimes expert at the Justice Department. He said it was not clear in the dispute exactly who controls access to the computers or whether the CIA's access to the computer system would have been illegal.
"It's not obvious that there's a criminal violation," he added.
The computer fraud statute has figured in, among others, the cases of Army Pvt. Chelsea Manning, who gave documents to WikiLeaks; whistleblower Thomas Drake, a former NSA official who disclosed government waste and fraud to a reporter; free-information activist Aaron Swartz; and Lori Drew, a Missouri woman who was convicted for her role in an Internet hoax involving a 13-year-old girl who hanged herself.
But the law also has been derided as ambiguous and overly broad in its reach, and federal appeals courts have split on how it should be interpreted. In Drew's case, a judge tossed out her misdemeanor convictions, citing the vagueness of the statute.
Exactly what authorized computer access means "is not defined, and it has produced a lot of uncertainty in a number of cases, and has been accused of encouraging prosecutorial excess because of the lack of definition," said Stewart Baker, a former National Security Agency general counsel who also served as assistant secretary for policy in the Homeland Security Department.
Baker said arguments could be made for criminal prosecution if either the Senate staff went beyond what it was authorized to do on the computer network or the CIA exceeded agreed-upon limitations on its authority to examine the computers used by the Senate staff. But he said he'd be "very surprised if indictments resulted, unless it's quite clear that the parties who were doing this knew that they were acting in excess of the understanding and were doing it surreptitiously."
