Here's the
opinion published by the DOJ.
I haven't read the full thing yet, but at first glance, it appears to pertain to state lotteries, and the idea of states selling lottery tickets online to residents of that state, and not to other forms of online gambling.
I wouldn't get too excited or jump to any conclusions about this opinion. It doesn't amount to a repeal of UIGEA, or anything close to such a sweeping change.
