re: Has govt ever defied a president like this?

What actions have been out of the ordinary other than the 7 country travel hiatus meant to review the vetting process?

Here's a conversation I had with one of my children about this in bullet points.

-#1 role of FedGov is to protect the US
- President is leader of FedGov and citizens
- IF, I said IF, he really thinks that the vetting process has holes or needs reviewed for improvement how can I be mad at him for doing what he thinks is right for the country. Now, IF, I said IF, he is doing this to be mean to Muslims and that's his sole motivation then I will not support such actions.

Which of the two ifs is more likely and I left that decision up to the child.
