I just sent the American Thinker link to Drudge. I hope others will do the same!
I read a story the other day that border agents interviewing these kids found pretty much the same story everywhere, that the kids and parents had been told that there was a “new law” allowing minors to come into the country, but only for a certain time. WHO has been spreading this rumor throughout South America? Of course, it might not have taken much spreading, since it’s something they’d love to believe ... but I think it highly possible some turncoat has been “spreading the word” to all the poor people in SA. We need to try and find where this rumor originated. That will tell us a lot.
I'd start with the PR section of the local USA embassy.
