Brock’s motive is different from Priebus’s, of course. In addition to heading MMFA, Brock is the chairman of American Bridge super PAC, which recently launched an effort called “Correct the Record” to protect Clinton and other Democrats from “Republican smears.” In his letters to NBC and CNN, Brock suggests that the “right-wing noise machine” is already pressuring those networks “to adopt its ideological lens on Clinton.”

“Given that this project could coincide with a potential Clinton campaign, the timing raises too many questions about fairness and conflicts of interest ahead of the 2016 election,” Brock writes in letters to both NBC Entertainment chairman Robert Greenblatt and CNN Worldwide president Jeff Zucker, which were obtained by POLITICO.
