ABC reports that the FBI was told 12 years ago that Katrina Leung was secretly working for the Chinese.

Now-retired FBI agent I.C. Smith says the FBI learned then that Leung had tipped off Chinese authorities about a secret mission he took to China to evaluate embassy security. He says he even took still photos of the Chinese agents he caught following him. "They knew we were coming before we even left," I.C. Smith said. Traveling with him to China, it turns out, was the other now-retired FBI agent accused of having a secret sexual relationship with Leung, William Cleveland of San Francisco. It was clear to him, I.C. Smith said, that at least 12 years ago a pretty big warning flag went up to the FBI. "There's no doubt about it," he said. "And I viewed that as absolutely a monumental management failure within the FBI that allowed this source to continue to operate."

Leung was indicted today on five charges, including "two counts of copying defense-related documents with reason to believe they would be used to the injury of the United States or to benefit a foreign nation and three counts of unauthorized possession of documents relating to the national defense."

We find it curious that Leung has not been charged with espionage. We suspect this is due to the Government's desire to avoid having to disclose classfied information to the defense.
