Its not just been reported by CNN, but by Fox, National Review, Washington Examiner, etc. as well. And electronic documents on the filing are in some of the news reports, like the Fox news web report.
People file legal claims all the time, even spurious ones with no basis, or with the intent of drawing attention to a cause. I believe one of the law firms is a human rights focused law firm, all the lawyers would need would need though is to find individuals in the group willing to be the plaintiffs in the suit, and make it class action so others can be added to it.
So I'm a little confused here as how the media has undermined its own credibility by reporting on what appears to be a true news story...?
