The national guard is part of the military, so funded and supported by the feds. Unlike normal army units though, each state or territory has its own national guard unit under the command of the governor. The intention is to give each state the power to quickly respond to emergency situations without needing federal approval. They’re the successors to the old state militias, but have much stronger federal ties now.
Sad to see down votes for the truth. The feds print the money so they don’t absolutely NEED to collect it first. But if money going out is more than the money coming in through taxes, it increases the supply and decreases the value of each dollar.
