Today’s budget release is only one step of the overall process. As mentioned above, a more comprehensive budget is still pending. Both the House and Senate will weigh in on the proposal, make changes, and send a final version back to the president for a signature. Additionally, Congress has yet to solidify a budget for fiscal year 2017, having passed a series of continuing resolutions to fund most of the government at 2016 levels.

But today’s announcement is still significant because it acts as a starting point for Congress. Overall, the Trump budget calls for defense spending to increase by 10 percent, while some federal agencies like the EPA stand to take major hits.
