Protesters do your research, these 7 countries involved, harbor and support ISIS, and yes they are muslim countries, bottom line including 911 and the following 48 islamic based attacks in the U.S. we are close to 4,000 innocent victims due to extreme islamic ideology. Trump is following thru on his vow to combat terrorism and justifiably so, the majority of americans are still for extreme background checks and for all  immigrants which includes flying in. Bottom line if wasn't for extreme islamic ideology there wouldn't be an issue, how many more innocent lives must be taken before you catch on ?? Thank you President Trump for your vow to protect this country, bottom line if you have an extensive criminal record or support any islamic terrorist ideology we don't want you here
