I asked the same question I got some interesting responses. The main link I have found so far is a woman named Sarah Latham.

Sara was John's cheif of staff http://www.p2016.org/clinton/clintonorg.html She was also the PR director at Freud Communications run by Freud's Grandson Matthew. https://en.wikipedia.org/wiki/Freud_Communications Clement is Freud's son.

Podestas chief of staff = PR Director for Freud Communication

Heres some of the best info I found somewhat summarized from another post;

Sarah Latham - Special Assistant to White House Chief of Staff John Podesta and Deputy Assistant to the President and Deputy Director of Presidential Scheduling from 1996 to 2000

2005 Sarah Latham worked for Tony Blair on his re-election campaign quits job as **Director of Public Affairs at Freud Communications **to work with UK Labor Tessa Jowell.

Founded Latham Group in 2006. Special Advisor to the U.K. Secretary of State for Culture, Media and Sport.

November 2008 Sara Latham ex director from Freud is taken on by the Obama / Democratic party transition team

November 2008 John Podesta serves as co-chair of same Obama transition team

1 January 2014 John Podesta becomes the Counselor to President Obama

2015 - 2016 Sara Latham ex-Freud becomes Podesta's chief of staff date not yet confirmed but definitely 2016 ready in time for the presidential run.

Actually, the only thing I can find are the words of FBIAnon.
