Since paying our debts is Constitutionally mandated the President would be required to pay these first...

Fourteenth Amendment, Section 4:

The validity of the public debt of the United States, authorized by law, including debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion, shall not be questioned.
