This is not right. America was not built on this principle. I noticed that the ban is on countries that did not partake in the 9/11 tragedy. I believe those countries were left out due to interests that our so called president has a monetary stake. Undo the ban now. I'm not happy with how no one is holding the so called presidents' feet to the fire to clean up his act. This is not grade school. I have participated in a march and will continue to do so.
