WASHINGTON, D.C. - Obama claims documents leaked from the military and posted to the website WikiLeaks could jeopardize citizens and operations.
The documents detail U.S. strategy in the war in Afghanistan, and information about targets and war partners.
Admiral Mike Mullen, Chairman of the Joint Chiefs of Staff said he was appalled by the disclosure of more than 90,000 secret U.S. military documents.
A Pentagon spokesman says the military has launched "a very robust investigation" into the leak of Afghanistan war secrets but doesn't know who's responsible.
Geoff Morrell tells CBS's "The Early Show" the broadcasting of this information poses a substantial hazard to American fighting forces in the wartorn country.
Morrell says the document drop "involves secrets that should not be disseminated into the public domain and could potentially endanger our operations and our forces in Afghanistan." He says that even most recent of the leaked documents "is at least six months old by now."
