Sean Spicer, Donald Trump’s press secretary, previously said it was a ban. Trump said even today it was a ban, but oh wait… Today Sean Spicer says it isn’t a ban.
If anything it’s embarrassing and looks of incompetence. 
When members of the press tried to ask why both he and the President had both repeatedly used the word “ban” and now deny that it’s a ban, Mr. Spicer walked out of the room and took no further questions. 
So is it a ban or not?
And the answer is yes and no. 
Clearly it is not a ban on all Muslims entering the country since the countries with the largest Muslim population were not included. Countries like Saudi Arabia, India.
According to Wikipedia:

“The largest Muslim population in a country is in Indonesia, a nation home to 12.7% of the world’s Muslims, followed by Pakistan (11.0%), and India (10.9%). About 20% of Muslims live in Arab countries.”

None of these countries were included in the ban.
But the six countries that are included in the ban are places to were ISIS tends to flee. And you heard it here first. 
So yes it’s a ban, but strictly speaking not a ban just because someone is Muslim.
