No, those two articles are by the former Assistant United States Attorney for the Southern District of New York and law professor at the New York Law School and Fordham University Law School.
"The law isn't an equation." Don't look now, but you're dissolving into the ever wishy-washy la la land of "everything is relative - especially when the facts are against me."
Read the law, again.
Section 1182(f), Title 8, U.S. Code - states, "Whenever the President finds that the entry of any aliens or of any class of aliens into the United States would be detrimental to the interests of the United States, he may by proclamation, and for such period as he may deem necessary, suspend the entry of all aliens or any class of aliens as immigrants or nonimmigrants, or impose on the entry of aliens any restrictions he may deem to be appropriate."
The law is clear and unambiguous. According to the law, President Trump absolutely has the authority to issue the EO that he did - period. So, you have missed the point. That is the law - whether you like the law or not. If you don't like it, then you are free to advocate for its change.
Meanwhile, what is being shown by all of this childish whining by those on the left side of the aisle about clearly constitutional EOs issued by President Trump ... when they were quite happy about all of President Obama's EOs - many of which were clearly unconstitutional ... is that to leftists the law is relative depending on their political whims du jour. Such leftist hypocrisy is being recognized by more and more Americans with each passing day.
