Defense Secretary Robert Gates announced today that he's asked the FBI to join the Wikileaks investigation, vowing to prosecute whomever is found to have played a role in the leak.

Gates said he has brought in the FBI to ensure that the investigation can "go wherever it needs to go," potentially to subjects outside the military sytem. He would not address whether journalists or Wikileaks founder Julian Assange might be charged.

But Adm. Mike Mullen, chairman of the Joint Chiefs, did lash out personally at Assange and his source, saying they might "already have on their hands the blood of some young soldier or that of an Afghan family."

Both Mullen and Gates said the leak would force the mlitary to review how it distributes intelligence to the front lines.

The military's practice in recent years, Gates said, has been to "push as much information as far forward as possible."

The question now is, "Should we change the way we apporach that, or do we continue to take the risk?"
