Executives from ABC News, NBC News, CBS News, Fox News and CNN spoke on Monday to compile a list of demands they will make to Donald Trump’s campaign in response to continued efforts to restrict the press.

On a call, senior representatives of the five major news networks discussed recent restrictive actions taken by the GOP presidential candidate’s campaign and how they should respond. It’s not clear what demands were formed by the group of network honchos.

Last week, campaign manager Corey Lewandowski threatened to blacklist CNN reporter Noah Gray for straying away from the designated “pen” for journalists.

Political campaigns trying to restrict reporters to zoned off areas at events is nothing new, particularly during presidential campaigns.

Trump has also made an adversarial relationship with the press one of the tenets of his campaign, tossing Univision’s Jorge Ramos out of a press conference in August.

None of the networks who spoke today immediately responded to TheWrap’s request for comment.
