Political messaging isn’t what it used to be. Far from it. It used to be that the front pages of The Washington Post and The New York Times were an agenda for action. This power was feared and used by successive presidents in my time, from Lyndon Johnson to Joe Biden, but not by Donald Trump.

Before Trump, there were several ways a president spoke to the nation. He either made a speech, held a press conference or leaked an idea to one of the two newspapers that counted in the Washington firmament, The Times and The Post. If that balloon floated upward, something formal followed.

Until Bill Clinton, that was often a speech at the National Press Club, a few blocks from the White House. Clinton never gave a major speech at the Press Club. That was the end of an era, the end of the Press Club as the forum of choice for presidents and heads of state.

In Clinton’s case, this wasn’t a failing of the Press Club system; it was just that it had become cumbersome and unnecessary. Clinton said it was simpler for him to talk to the nation from the White House formally in a press conference in the East Room. Less formally, he could walk into the Brady Briefing Room, where the press was on duty all day and the network cameras were ready to roll.

Technology was changing the way news came out of the White House. While Clinton preferred press conferences or informal presentations, the two dominant newspapers were essential tools to him, as they had been and would be to other presidents until technology again changed things.

I watched the system of trial-by-leak from the Johnson through the Biden years, although things were somewhat different under Bush. There was a new newspaper in town, The Washington Times, which was avowedly conservative, which caused George W. Bush’s staff to lean that way.

However, the new paper didn’t change the system in which a top White House correspondent would be leaked a story. If it failed, it wasn’t heard about again; it would either die in the aridity of silence, or it could be mildly denied as “speculation.”

None of this was ever laid out formally, but it worked and worked for a long time. It gave the president cover and the reporter a payoff with “access.”

With Trump, things are different, primarily because of his seemingly narcotic addiction to publicity but also because technology has bypassed the media of old: the newspapers and the hungry cameras.

Trump has Truth Social, and his aides have X. He makes announcements all the time, changes direction, denies former positions and doesn’t test ideas before sharing them. It is dangerous and giddy, but clearly, it delights Trump.

It has created the kind of yo-yo of yes-no-yes-perhaps that we have seen most recently with Trump’s statements about whether he would or wouldn’t try to fire the chairman of the Federal Reserve, Jerome Powell.

The now-nightly Niagara Falls of unformed presidential thinking on Truth Social has changed the role of the press corps.

From leading the day’s news to following it, the press corps has seen its role change and its significance diminished. The media giants are now forced to follow like hyenas, not hunt like lions. They are following the hunt, not heading it.

Whereas when ideas were tested through media, presidents could be saved from some of their worst inclinations, now there is no restraint, not even the thin membrane provided by a diligent press secretary, suggesting caution or at least preceding thought.

From his early days in real estate in New York, Trump has craved publicity, grooved on it, and seen it as an end in itself more than a means to an end.

In a naive moment when the National Press Building was in financial trouble, which was at one time owned mainly by the Press Club, I suggested to some colleagues that we sell the building to Trump — not Trump the politician but pre-political Trump.

Fortunately, some of my colleagues had dealt with Trump and knew about his media bullying — he would even call into New York radio talk shows and talk about himself as though he was someone else — and warned that our lives would be hell and the club would be used by Trump, if he could, to glorify himself.

Now, we see Trump converting the Oval Office, heretofore an inner sanctum, into a kind of television studio, himself enthroned at the center.
