CURIOUSER AND CURIOUSER: Obama-era uranium deal yields new questions, new accusations and new investigation.

FBI investigations are typically not disclosed at the time they are ongoing, so it is possible that the government officials involved in approving the Uranium One deal were not aware of the criminal investigation at the time of the approval. CNN spoke with Ronald Hosko, assistant FBI director in charge of criminal cases at the time of the investigation, who said that he wasn’t aware of the ongoing probe, saying it was handled on the counterintelligence side of the bureau. Counterintelligence investigations are some of the most closely held in the FBI. Former Rep. Mike Rogers, R-Michigan, who chaired the House Intelligence Committee at the time of the probe, also told The Hill that he was never informed about the FBI probe either.

The informant who played a crucial role in the FBI investigation is now trying to speak out, but his attorney says he is barred by a non-disclosure agreement the FBI made him sign. A law enforcement source familiar with the process said it is common for cooperating witnesses to sign non-disclosure agreements when the investigation involves national security concerns, as it did in this case. However, these agreements are typically narrowly written, and do not typically prevent individuals from speaking to Congress about what they learned in the ordinary course of business while simultaneously working as an informant, the source said. However, the source says the agreement would prevent any disclosure of information that was gleaned while working closely with federal investigators as it pertained to the investigation itself.

The informant’s attorney tells CNN the informant has a lot of information about corruption that has not come out yet. In particular, the attorney maintains that while the FBI investigation was going on, FBI agents told the informant that President Barack Obama was being briefed on the probe, and that’s why the informant was so stunned when the Uranium One deal was approved in 2010. Obama’s representative declined to comment.

That’s an awful lot of official silence for something which Hillary Clinton says is “baloney.”
