There is no “existential risk” clause in the Constitution. And I’d argue (as I did above) that the $28 trillion national debt we owed in the last year of President Trump’s first term was less of a risk only by a degree.
What if Biden or his autopen decreed that due to a $30 trillion debt, to save the nation income tax rates would be raised by 50% across the board?
The courts should then be sanctioning Congress to do their Constitutional duty, not attacking the Execuative.
Congress gave him this authority.
