As of last week, the American public had been told that President Trump’s doctor had certified he would be “the healthiest individual ever elected.” That the president was happy with his legal team and would not hire a new lawyer. That he did not know about the $130,000 payment to a former pornographic film actress who claimed to have had an affair with him.

As of this week, it turns out that the statement about his health was not actually from the doctor but had been dictated by Mr. Trump himself. That the president has split with the leaders of his legal team and hired the same new lawyer he had denied recruiting. And that Mr. Trump himself had financed the $130,000 payment intended to buy the silence of the actress known as Stormy Daniels.

Even in the current political environment that some derisively call the post-truth world, the past few days have offered a head-spinning series of revelations that conflicted with the version of events Mr. Trump and his associates had previously provided.
