"The protesters are great, but if I can't see my dad coming out, then it's kind of missing the point," Bardia Noohi said.



As protesters marched through the arrivals gate, the Noohi brothers took video of them.



Another person held, Abdulsalam Mused, 67, of Oak Lawn, was freed after more than six hours of questioning, and he stopped to shake hands with the volunteer attorneys and protesters. He said authorities repeatedly asked him whether he was carrying weapons and whether he had visited his native Yemen while on his trip to Saudi Arabia for his son's wedding.



He said he was treated nicely, but the experience still left him shaken.



"I received political asylum in the United States because I stood up to terrorists in Yemen," said Mused, who has lived in the U.S. for 18 years. "This is the first time in my life that I was made to feel like a terrorist."



Wearing a pinstripe suit and tie, Mused encouraged the president to rescind his order. "This is not what America is about," he said. "America is about freedom of expression and freedom of religion. It's a country of immigrants. It's not this."
