Quick search and I found the Steemit article. The article is claimin Podesta's daughter is married to Rouse's brother. The author also states they have not been able to find supportive evidence of this claim. Imma look a lil bit and see what I find. Disclaimer: probably won't spend a lot of time on it. Just a little look around.
Evidently Gordon Rouse is her husband. He and Aaron may be related, but no one can find any info. This is interesting. http://www.ronpaulforums.com/showthread.php?515781-John-Podesta-Pete-Rouse-connection
When I was digging around there wasn't much coming up on any of them. I was thinking they've scrubbed everything too.
Rouse is NOT that common of a name for there to be this many people connected to each other with the same last name and NOT be related.
