According to the latest Fox News poll, 68% of Americans are concerned the President has exceeded his constitutional authority in his executive amnesty scheme. The President himself said it would unconstitutional before he did it.
Republicans members of congress agree. They too say the President’s actions are unconstitutional. They swore an oath to uphold, protect, and defend the constitution.
Therefore, should they fund the President’s unconstitutional actions they will be violating their oath to the constitution.
This is not complicated. The Republicans in the House of Representatives will either honor their oath of office or they will not. It is not hard.
