Extract from a piece in the New Yorker

Donald Trump is hardly the first President to lie to the American people. Nor is he the first to place ideology before data. But this White House, unlike any other, has already crossed the threshold into a space where facts appear to mean nothing.

Eventually, the President’s daily policy outrages, his caustic insults, and his childish Twitter rants will fade into history. But it will take years to gauge the impact of having a habitual liar as President. When words like “science” and “progress” become unmoored from their meaning, the effects are incalculable. And let’s not kid ourselves: those words today are under assault with a ferocity we have not seen for hundreds of years.

The United States is now a country with dozens of unofficial government “resistance” Twitter accounts. There is one for the National Aeronautics and Space Administration, another for the Environmental Protection Agency, and others for the National Park Service, the Peace Corps, and the Customs Agency. Last week, in what the account describes as an effort to present “actual facts, instead of alternative facts,’’ they were joined by the nation’s most important public-health agency, the Centers for Disease Control and Prevention.

There are horrific lies of omission: last week, the White House released a statement on International Holocaust Remembrance Day that pointedly declined to refer to Jews, because others were killed, too. And there are denials of truth that are impossible to categorize: the President met with Robert F. Kennedy, Jr., an anti-vaccine zealot with a history of falsehoods, and talked to him about possibly forming a commission on vaccine safety. (After Kennedy said he’d actually been asked to lead such a commission, provoking dismay, the Trump team said that no decision had yet been made.) Then there are lies so ludicrous that it is hard (though essential) to take them seriously: according to Trump, the United States has just gone through the most devastating instance of voter fraud in the nation’s history. And, in his telling, every one of the millions of illegal votes happened to be cast for Clinton
