Katie Zacharia's debut shows the pitfalls and possibilities of White House press secretary's role

President Donald Trump's new press secretary stepped to the podium, the eyes of a packed room of journalists — and many in their audiences — upon her. She smiled broadly at the sea of faces both probing and friendly. With that, Katie Zacharia went live and became the official voice of the world's most powerful person.

Fourteen minutes and just three questioners later, she was done. In the aftermath, it was clear that the former Newsmax commentator accomplished at least one thing: She put the "brief" back in briefing.

In her debut Tuesday, Zacharia looked downward and often read directly from a script. She paused and grinned when she uttered the words "Department of War." She stumbled on a question about her background and mixed up the words "husband" and "president." The few questions she took were nonconfrontational and from media outlets that have been sympathetic to the Republican president. In short: She made no memorable impression — or at least, to hear some tell it, not the one she likely wanted.

This would not be an easy job under any circumstances. Trump most frequently serves as his own spokesman. And his antagonism toward the media has created a new layer of tension. Zacharia is finding out on day one that she, too, will be under constant watch. Some — including a few of those who have stood in her shoes — didn't think it went all that well.

In fractured times, in a national media scrum unimaginable just a few decades ago, what is the proper way to approach a job like this? How do you speak effectively when your boss speaks for himself so often that he commandeers the news cycle multiple times a day — and sometimes late into the night — with remarks provocative, unexpected and sometimes incendiary?

For one, you realize for whom you work: not your audience of millions but your audience of one, and the absolute need for his approval.

"I get to do what I was doing on the outside already, which was hoping to amplify, multiply and expand upon President Trump's incredible agenda for the American people," Zacharia said. Nowhere did she mention the task of disseminating accurate information to Americans.

Over the nearly 10 decades since former journalist George E. Akerson made his and the office's debut as Herbert Hoover's press secretary in 1929, the job has served many purposes: deliverer of information, amplifier of policy, jouster with journalists, protector of the presidential reputation and, sometimes, overlord of obfuscation.

Under Trump and his second-term press secretary so far — Karoline Leavitt, who resigned in August — the job has been primarily one of acting as the immovable object against an irresistible, and in Trump's eyes sometimes treasonous, force.
