There were numerous previous attempts to obtain general information about the budget. As a result, it was revealed that CIA's annual budget in Fiscal Year 1963 was US $550 million (inflation-adjusted US$ 4.3 billion in 2016), and the overall intelligence budget in FY 1997 was US $26.6 billion (inflation-adjusted US$ 39.2 billion in 2016). There have been accidental disclosures; for instance, Mary Margaret Graham, a former CIA official and deputy director of national intelligence for collection in 2005, said that the annual intelligence budget was $44 billion, and in 1994 Congress accidentally published a budget of $43.4 billion (in 2012 dollars) in 1994 for the non-military National Intelligence Program, including $4.8 billion for the CIA. After the Marshall Plan was approved, appropriating $13.7 billion over five years, 5% of those funds or $685 million were made available to the CIA.
