As surprisingly mentioned in the MSN article, last summer SCOTUS blocked the district court injunction from using the funds. SCOTUS said they could continue using the money and building the wall pending appeal. Not surprisingly, the 9th Circuit agreed with the District Court so the injunction is on again.
SCOTUS was 4-5 Decision along predictable party lines. (Oh, I forgot; they are non-partisan!) Decent sign they might overrule the 9th, unless Roberts think it will make him look bad. Post-election likely.
Ignore it. What they gonna do? Send a strongly worded letter? Impeach him? Trash him in the media for more poking points.
