That's not Trump's entire tweet, hence the ellipsis at the end. Twitter limits tweets to 280 bytes, causing Trump's tweet to span 3 tweets. Here's the entirety of those tweets...
Mr. Cohen, an attorney, received a monthly retainer, not from the campaign and having nothing to do with the campaign, from which he entered into, through reimbursement, a private contract between two parties, known as a non-disclosure agreement, or NDA. These agreements are very common among celebrities and people of wealth. In this case it is in full force and effect and will be used in Arbitration for damages against Ms. Clifford (Daniels). The agreement was used to stop the false and extortionist accusations made by her about an affair, despite already having signed a detailed letter admitting that there was no affair. Prior to its violation by Ms. Clifford and her attorney, this was a private agreement. Money from the campaign, or campaign contributions, played no roll in this transaction.
