All fine and dandy, except the Congress is not aligned solidly at Trump’s back.
Should he proceed as you suggest, they will impeach and convict him.
Every institution in America is corrupted.
Where’s your alternative suggestion? It’s not enough to say something essential won’t work if you haven’t thought through a viable alternative.
Meanwhile, barring a better, viable alternative to Trump moving ahead on this, a Congressional impeachment of Trump would be without constitutional merit as Trump is the only party in this case trying to uphold the Constitution.
The answer is Trump should take his case to the American People citing Article IV Section 4 of the Constitution MANDATING the feds PROTECT the U.S. from invasion. Trump should urge his fellow Americans to call their congressmen to support his efforts to protect the American People and ask Congress to fix the existing law or pass a new one pursuant to Article IV Section 4.
