Leak Probe More Than 2 Years Old (washingtonpost.com)
For more than two years, the FBI has been investigating whether classified intelligence has been passed to Israel by the American Israel Political Action Committee, an influential U.S. lobbying group, in a probe that extends beyond the case of Pentagon employee Lawrence A. Franklin, according to senior U.S. officials and other sources.

The counterintelligence probe, which is different from a criminal investigation, focuses on a possible transfer of intelligence more extensive than whether Franklin passed on a draft presidential directive on U.S. policy toward Iran, the sources said. The FBI is examining whether highly classified material from the National Security Agency, which conducts electronic intercepts of communications, were also forwarded to Israel, they said.
