evidence: While it is true that the BCA has affected defense capability somewhat, its effect has been mitigated by two factors. First, Congress granted the Department of Defense more than $200 billion in relief between 2013 and 2017 from the spending caps; and the FY 2018 base defense budget exceeds the caps by another $100 billion. Second, the Pentagon has used the Overseas Contingency Operations (OCO), or warfighting, account to get around the caps. According to the Department of Defense comptroller, about half of the OCO account has funded Pentagon programs that have nothing to do with the wars in Iraq and Afghanistan. For example, the European Deterrence Initiative has been funded in the OCO account since FY 2017, when the Pentagon received $3.4 billion for it. The Pentagon admits that even with the large increase in the FY 2019 base budget, $17 billion of this year’s OCO account contains items normally funded in the base budget. President Trump’s own Office of Management and Budget director, Mick Mulvaney, has labeled the OCO account a "slush fund."
