Reporter what the real ben is up to is a departure from those roles, traveling to meet with Syrian Refugees in jordan. He was there to support the United Nations refugee agency, unhcr, where 35,000 syrians have fled years of bloodshed and the horrors of isis. Including mohammad ssala and hi wife ha engineer, and their two kids. Ged byombing that yes were happened near they are home. Theyre trying to get medical care for him. Hala what she said to me was, we just want a chance to move forward, we just want a chance to live our lives. And she was crying when she was saying it. She was so passionate about it. What impressions were left with you . When we were there, they still didnt have electricity. They were just getting their solar grid panel up and running. No toilets, no running water. They showed me their bathroom, which is like a plastic cup with four toothbrushes in it. The other idea is, okay, fine, these people may be safe, but what if terrorists sneak across the lines with them . Are we just letting in terrorists . Well, we havent done that yet. And theres an extreme vetting process that goes on. Every refugee who comes into america has gone through multiple vettings by the fbi, homeland security, after theyve been through the u. N. Process. President trumps executive order blocking Syrian Refugees indefinitely, and barring citizens from seven muslim countries. Protests immediately erupted at airports across the country. Friday a federal judge in seattle blocked president trumps order temporarily. The state has met its burden of demonstrationing faces immediate and irrep ran injury reporter opening the doors once again to families caught in the middle of a legal showdown between the white house and the courts. Emotional reunions over the weekend in the u. S. Over the weekend, the trump administrations lawyers appeal as the president tweets, the opinion of the socalled judge which essentially takes Law Enforcement away from our country is ridiculous and will be overturned. Hours later, tweeting again. Because the dan was lifted by a judge, many ver dangerous people may be pouring into our country. Disagree with this judge. I think its okay to say, this is a horrible decision. But to say socalled judge, suggesting that the judge is illegitimate, thats where you get into scary territory. Where it sounds like the president is saying that the courts are either illegitimate or shouldnt judge. Undermining the judiciary. Absolutely. Reporter some think the case could go to the supreme court. If the administration would come forward with a moredetailed, well thought out order, i think they might be in better shape right now. Because the president does have enormous autonomy when it comes to immigration. I feel like this is a human issue. Its not a political issue. Reporter stiller is months the only star sounding the alarm about the refugee crisis. Three bags. Reporter in this hcr video, actors speak out on behalf of refugees. The most painful thing about being a refugee is you wake up one day to find youve lost all your liberty and can no longer decide on your life. Its like everything is closed in your face. What do you think of Donald Trumps attacks on many people in the hollywood community, including meryl streep and others who dare to speak out . His view is, you guys are celebrities, you need to youre not experts, you need to keep quiet on this. Yeah. Its kind of ironic. I dont want to criticize the president , hes the president. I think its ironic because obviously he himself is a celebrity. But to me its a greater issue. Now that hes the president and leader of the free world, i think america has to set the example. And we always have. With refugees. Reporter today in a joint declaration to the federal appeals cou president s order, several former National SecurityOfficials Say since september 11th, 2001, not a single terrorist attack in the United States has been perpetrated by aliens from the countries named in the order. If you really look at the record of terrorist violence in america in the last 15 years, none of it relates to refugees. I think this idea that refugees coming into our country equals, as the president said in a tweet, death and destruction, is just wrong. Reporter and after the judge lifted the travel ban, stiller wanted to talk to us again. I think people are having this are voice heard, from the man in the street all the way up to the highest levels of government who really disagree with the ban. So youre seeing democracy in action. Reporter and stiller says now that hes found his political voice, he plans to keep speaking out for those who cant. And its hard to leave those people in that place because its a real thing. Theyre still stuck there. I think its really unfor that its become politicized. Because it is a humanitarian issue. Thats the bottom line, these are peoples lives. And our country as always been a mace thats accepted people fleeing persecution and war. Thats who we are as a country. Reporter for nightline im juju chang in new york.
