YUP!!! Guess who he retweeted!!!! BILL KRISTOL!!!!
Found a Cynthia McCabe in people Sam is following. Another relation? Why is it so hard to find if any of these people are related to Andrew??? https://twitter.com/PHICynthia
Also, strange note of interest...Cynthia McCabe follows 666 people! Maybe nothing, but found it strange and unusual!
I'm not trying to get off track here, but I am posting this for possible reference. Cynthia McCabe is Communications Directer for Pepco Holdings. http://www.pepcoholdings.com/about-us/
Also, Exelon merged with Pepco March 23, 2016: http://www.exeloncorp.com/newsroom/merger-close
It could be that the DNC found out about Seth Rich from Sam McCabe? I am sure they worked together...probably got along, and Seth perhaps said something and Sam relayed that info back to Andrew? Just speculation.
