1. President Trump contradicted his earlier statements that he knew nothing of a payment to Stormy Daniels, the pornographic film actress who says she had an affair with him.

Writing on Twitter, Mr. Trump suggested that the payment from his lawyer, Michael Cohen, came from a monthly retainer he paid and could not be considered a campaign contribution.

The tweets had far more formal and legalistic language than his typical morning messages to the world, and came after one of his attorneys, Rudy Giuliani, said the same during an interview on Fox News.
