CBS News initially reported Tuesday that Chalabi had told an Iranian intelligence official that the United States had cracked its codes, allowing U.S. agents to read Iran's secret communications.

Revealing such information would expose one of the United States' most important sources of information about Iran.

Following the broadcast report, The New York Times, Los Angeles Times and The Washington Post followed with similar stories, all quoting anonymous U.S. intelligence officials.

American officials quoted in the news reports said Chalabi told the Baghdad chief of the Iranian spy service that the United States was reading its communications and that the Iranian spy described the conversation in a message to Tehran, which was intercepted by U.S. intelligence.

The New York Times account said Iranians in Tehran then sent a bogus message to Baghdad purportedly disclosing the location of an important weapons site, in an apparent attempt to test whether what they were hearing from Chalabi was true.

The idea was that if the United States was able to intercept such transmissions, Americans would react by going to the weapons site. They intercepted the message, according to the Times, but did not take the bait by going to the weapons site.

Chalabi reportedly told the Iranian he had he had gotten the information from an American who had been drunk.
