The answer is to cut out the middlemen. Let Trump be Trump.
Donald Trump should serve as his own press secretary and maybe his own chief of staff. I would even propose that the Trump presidency go live to the world, with a camera crew recording the president and his moment-to-moment thoughts in real time every day. President Trump as messenger in chief.
A month ago, this proposal would have been read as satire. But it is now close to the manifest reality of the Trump White House.
If Mr. Trump says or tweets something that causes a stir, such as pulling out of Nafta, let him talk to reporters on his terms to explain what he meant. If he changes his mind in minutes, hours or days, he can turn to the real-time camera and do it. But he takes responsibility for the Trump message.
