On February 9, 2016, President Barack Obama released his budget proposal for the 2017 fiscal year. Facing a Republican Congress, many declared the plan "dead on arrival." Among the cited issues was Obama's request for $582.7 billion in discretionary spending for defense, which many Republicans believed was not enough. Which of the following most accurately explains the interaction between the president and the Congress regarding the defense budget? 1) Congress passes a budget for the entire federal government, including defense, but it must consider the president's proposal because the president may veto the bill.
2) The president introduces a specific budget bill for defense spending, but Congress uses its power of legislative oversight to set up a negotiation process with the president.
3) Congress has the enumerated power to raise revenue, but it is forced to work with the president because the president has the power to determine spending for each department in the upcoming fiscal year.
4) The president can create a budget for defense spending, but Congress has the power to execute laws and operate the government, which can affect how much money is actually spent.
