I think that it's commonplace in a lot of jurisdictions that even illegal aliens have some human rights. I understand that people aren't happy that they are in the country, but I don't agree that they "siphoned" the money out of the economy. They worked for it and were paid for the work, it's not like they robbed a bank. (You could make the argument that they had a job that "rightly" belonged to someone else, but to me that's far from a convincing argument.) But I take your point, they are not in the same legal category as citizens, notwithstanding the arguments of the economists who do NOT think that they cost the county anything. And if they don't cost the country anything, my thinking goes, why this much fuss? Do something about it if you want, sure, but I remain unconvinced that it's a pressing issue of great magnitude.
But it is difficult for me to believe that the US is really going to track down and deport all 13 million (or whatever the number is), it's about as likely as getting Mexico to pay for a wall, assuming a wall ever gets built. So at some point, an accommodation is going to be reached.
(Do you know if the remittance amounts mentioned earlier included only remittances from illegal aliens or did the amounts also include remittances from legal Mexican immigrants? It seems to me that the latter can send the money to whoever they want, and it's none of anyone's business.)
As for declaring that journalists are violating the country's secrets, in this case it seems like a stretch to me. It's all too easy for politicians to declare personally embarrassing things to be secrets, isn't it? It's happened before, I'm sure. I don't know the details of this one, I can't honestly say I've followed the whole Russian/election thing much, but at first glance, it doesn't seem to me as if important state secrets are at stake here. We'll see, I guess.
