I had to see for myself, so I read the executive order. The order does seek “to protect the American people from terrorist attacks by foreign nationals admitted to the United States.” It says that it seeks “Suspension of Issuance of Visas and Other Immigration Benefits to Nationals of Countries of Particular Concern.”
The other six Countries of Particular Concern were listed as such BY THE OBAMA ADMINISTRATION!
What the Trump administration ought to, is tell the Federal Judiciary to take a hike. It has no power to interfere with Presidential or Congressional powers.
