I want to know the answer to the following question:
What was the first year the CIA's budget was disclosed?
All the background I'm provided with is that "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).". Is that enough to answer the question?
