Is Homeland Security a non-essential item??
It's probably essential because of all the agencies it has swallowed.
That's why it would be Dereliction of Duty for the POTUS to veto or Dems in the Senate to filibuster to preserve funding for an unconstitutional action that undermines the Rule of Law and the foundation of the republic.
The House would be correct to deny funding for lawless amnesty.
Do you disagree?
