Donald Trump's ban on Muslims entering the United States had meant that this woman is stranded. Planning to fly back from Costa Rica to Glasgow via New York, the executive order that Trump has signed means that, because she's an Iranian national, she's barred from entering the US. Having to pay an extra £2,600 to fly back via Madrid, she and her partner will struggle with rent, bills and food for the next few months. But this isn't just about making sure they're not evicted or cut off or that they don't starve. It's about the principle that a billionaire bigot is very quickly making the world a darker place. We can't stand for it. We all have to do something, even if it's just helping one person.
