Yes, Obama accidentally the document.
Here is the document blurb:
To the Congress of the United States:
I transmit herewith a list of the sites, locations, facilities, and activities
in the United States that I intend to declare to the International
Atomic Energy Agency (IAEA), under the Protocol Additional
to the Agreement between the United States of America and
the International Atomic Energy Agency for the Application of
Safeguards in the United States of America, with Annexes, signed
at Vienna on June 12, 1998 (the ''U.S.-IAEA Additional Protocol''),
and constitutes a report thereon, as required by section 271 of Public
Law 109-401. In accordance with section 273 of Public Law
109-401, I hereby certify that:
(1) each site, location, facility, and activity included in the
list has been examined by each department and agency with
national security equities with respect to such site, location, facility,
or activity; and
(2) appropriate measures have been taken to ensure that information
of direct national security significance will not be
compromised at any such site, location, facility, or activity in
connection with an IAEA inspection.
The enclosed draft declaration lists each site, location, facility,
and activity I intend to declare to the IAEA, and provides a detailed
description of such sites, locations, facilities, and activities,
and the provisions of the U.S.-IAEA Additional Protocol under
which they would be declared. Each site, location, facility, and activity
would be declared in order to meet the obligations of the
United States of America with respect to these provisions.
The IAEA classification of the enclosed declaration is ''Highly
Confidential Safeguards Sensitive''; however, the United States regards
this information as ''Sensitive but Unclassified.''
Nonetheless, under Public Law 109-401, information reported to,
or otherwise acquired by, the United States Government under this
title or under the U.S.-IAEA Additional Protocol shall be exempt
from disclosure under section 552 of title 5, United States Code.
BARACK OBAMA.

Amusingly, it is addressed to Congress. Which means it would have been leaked PDQ regardless.
