Donald Trump and his advisers have decided to work directly with television executives and take a lead role in negotiating the format and content of primary debates, which have become highly watched and crucial events in the 2016 race, according to Republicans familiar with their plans.

Trump plans to reject a joint letter to television network hosts regarding upcoming primary debates drafted Sunday at a private gathering of operatives from at least 11 presidential campaigns, the Republicans said.

The move by Trump, coming just hours after more than a dozen Republican strategists huddled in the Washington suburbs to craft a list of possible demands, effectively throttles an effort by the campaigns and the letter’s drafter, longtime GOP attorney Ben Ginsberg, to find consensus and work collectively to negotiate terms.
