1. The 90 day ban is for all entries not just refugees. You have no idea what he will or won't do.
2. $600 was what the MSM reported as the total cost of the operation, including the first year support costs I would imagine.
3. As I noted below the 25,000 was incorrect - the number is actually 50,000. And it is not just Syrians (give the moral imperative you display surely you wouldn't limit your offer to Syrian refugees and leave the other refugees  Trump is blocking to fend for themselves).
To your final paragraph: being middle class with possessions etc means they could have paid their own way here - I assume you saw how nicely turned out they were. They were also in no immediate danger so the haste to get them here by a political deadline was outrageous. As for the homeless - and yet I don't see you campaigning to do something about them... perhaps I missed all your earlier posts on that.
And again where is the money coming from and where will you put them???
