Could it be that POTUS will direct all gov and alphabet funding through a zero balance account to have total control of gov spending?
What is a 'Zero Balance Account - ZBA'
A zero balance account (ZBA) is a checking account in which a balance of zero is maintained by automatically transferring funds from a master account in an amount only large enough to cover checks presented. A ZBA is used by corporations to eliminate excess balances in separate accounts and maintain greater control over disbursements.
