John Kelly's big challenge: Controlling the tweeter in chief

But he knows, these people said, that he cannot stop the president from tweeting and sees a goal of “pushing the tweets in the right direction,” one White House official said, by limiting who encourages them.

Instead, Kelly has said he would like to know what Trump is planning to tweet before he does so and would prefer that big decisions not be announced on Twitter — but has privately conceded there will be late-night or early-morning missives he cannot review…

“You can’t have a president who gets up at 5 a.m. and tweets policy,” said Leon Panetta, a former chief of staff and a friend of Kelly’s. “The best thing would be if the president stopped tweeting, but that’s not going to happen.”
