Final answer:
The president would propose the program to Congress, who would review and potentially approve the funding through legislation.
Step-by-step explanation:
If the president wanted to use federal funding for a new military program, the program would need to go through an approval process. The president would first propose the program to Congress, who has the power to allocate federal funds. Congress would then review the proposal and potentially draft legislation to approve the funding. The legislation would go through a series of votes and debates in both the House of Representatives and the Senate, and if it passes, it would then be sent to the president for signature or veto.
