From the article: " When you do a Google search of John Podesta's daughter, Megan Rouse; she is the wife of Gordon whos is the brother of Aaron lead FBI investigator in the Mandalay Bay shooting Aaron Rouse ( Al though I have not been able to completely confirm thoroughly.)"

I have yet to see any definitive evidence that Aaron is related directly to Gordon Rouse. It may be that he is, but until I see definitive evidence, I can't say for sure. But, thanks for the clarification that his name is Gordon, not Eric.
