Today Attorney General, Eric Holder, discussed the case on
Face The Nation .
One part (4 min into interview) I found of interest was his discussion of the children of these 10 people, some of whom were born here and so were legally US citizens, and some were near adulthood or already were adults. He said these children were given their choice whether to stay in the US or to go to Russia with their parents, and they all decided to go with their parents.
This sounds a lot like what will probably happen with regards to the US-born children of "illegal immigrants", and some of the older children (adults) may very well decide on their own to stay in the US.
Some of the public may be unhappy about it, but this may be the most reasonable way to go in dealing with difficult family decisions.
