In a time of global emergency, we need calm, directness and, above all, hard facts. Only the opposite is on offer from the Trump White House. It is therefore time to call the president’s news conferences for what they are: propaganda.

We may as well be watching newsreels approved by the Soviet Politburo. We’re witnessing the falsification of history in real time. When Donald Trump, under the guise of social distancing, told the White House press corps on Thursday that he ought to get rid of 75 to 80 percent of them — reserving the privilege only for those he liked — it may have been chilling, but it wasn’t surprising. He wants to thin out their ranks until there’s only Pravda in the room.

Sometimes, I stare at Deborah Birx during these briefings and I wonder if she understands that this is the footage historians will be looking at 100 years from now — the president rambling on incoherently, vainly, angrily, deceitfully, while she watches, her face stiff with the strangled horror of a bride enduring an inappropriate toast.

If the public wants factual news briefings, they need to tune in to those who are giving them: Gov. Andrew Cuomo of New York, Prime Minister Justin Trudeau of Canada and Chancellor Angela Merkel of Germany, whose addresses appear with English subtitles on Deutsche Welle. They should start following the many civic-minded epidemiologists and virologists and contagion experts on Twitter, like Harvard’s Marc Lipsitch and Yale’s Nicholas Christakis, whose threads have been invaluable primers in a time of awful confusion.
