That is what my thinking was as well.

You should have seen the face of Alexander when he announced his opposition. He said there was no precedent that a president wanted money after Congress denied it. So he wants Trump to stand in line properly, to the mighty power Congress exerts.

I am sure Trump is not surprised at this charade.

My first thought was, "How much campaign funding were these senators promised by Soros and company?"
What could be an alternative motivation?
I have a major dislike for presidential emergency powers, which are not constitutionally granted. I could see that as a motivation under normal circumstances, but some of these senators are definitely motivated by politics, not constitutionality.
