Where Should We Cut Spending First?

The national debt is out of control - $20 trillion and counting. The deficit for 2018 is estimated to be $1 trillion. Reckless spending continues unabated under Republican leadership. This is utter madness! We MUST #StopSpending.
I need your help! Would you let me know where you think we should cut spending first? I want to hear your opinion. Thanks - Austin
