WASHINGTON (AP) - The Pentagon says top military officers and civilians had to sign a letter promising to keep budget details secret if they wanted to work on the military's fiscal plan.
Defense Department press secretary Geoff Morrell says Secretary Robert Gates set the rule - and that this year is the first time he required the non-disclosure statements.
The entire Joint Chiefs of Staff signed, promising not to leak information while the budget is being put together. Morrell says Gates also signed.
President Barack Obama plans to submit his budget to Congress on Thursday.
