Hillary Clinton campaign chairman John Podesta really dislikes Democratic operative and strategist David Brock, according to newly released emails that were illegally obtained by Wikileaks.

Podesta had been sent a link to a Politico article back in Feb. 2015 about Brock resigning from the Priorities USA Action Super PAC. Brock claimed at the time that officials at Priorities were conducting “an orchestrated political hit job” on Brock’s other groups, American Bridge and Media Matters, both pro-Clinton groups.
