Sen. Dianne Feinstein (D-Calif.), the chairwoman of the Senate Intelligence Committee, said on Fox News Sunday that the news was “like a lightning bolt” with no advance notice to the committees that, by law, are supposed to be informed of any significant development in the intelligence sector.

Feinstein confirmed there will be a committee inquiry into why the FBI sat on the news of the investigation for so long.

“The FBI has briefed me now. I actually wish we had been briefed a little bit earlier so that the full intelligence committee — one of the things I’ve tried to do, Chris, is bring both sides together. So, my vice chairman, Saxby Chambliss, and I share material and work together and that’s a very important concept,” she said. “With neither of us knowing ahead of time, all of this, obviously, comes as a big shock.”

Feinstein said she only found out when her office began receiving calls from the media about the Petraeus affair. A Friday afternoon appointment she had with the disgraced director was then canceled.

“This is something that could have had an effect on national security. I think we should have been told. There is a way to do it,” she said. “And that is, just to inform the chair and the vice chairman of both committees, to — this has happened before, not with precise, same things, but, none of the four of us have ever breached that confidentiality.”

The Associated Press reported this afternoon that the State Department’s liaison to the military’s Joint Special Operations Command allegedly received the harassing emails from Petraeus biographer Paula Broadwell that triggered an FBI investigation. The FBI probe into the complaint began several months ago.
