Many Republicans have been vehemently opposed to it. Take a look at the Supreme Court decision Gonzalez v.

What ever tactic is taken with respect to this Pact, we should be unsurprised if it ignores any "principles" and instead looks to effect the policy that Trump desires to put into place, or the effect on Trump's perception of his authority.
