Donald Trump appears to be banking on recent testimony by a lawyer, Robert Costello, to protect him from potential indictment from a New York grand jury. Costello testified as part of the Manhattan district attorney's office probe into hush money paid to adult-film star Stormy Daniels to keep an alleged affair she had with the former president a secret ahead of the 2016 election. An indictment from the jury could be announced in the coming days. Prosecutors are probing whether the money Trump arranged for his former lawyer Michael Cohen to pay Daniels amounted to a campaign violation or if any records were falsified when Cohen was reimbursed for the money, listed in Trump Organization records as legal fees. Trump is at risk of becoming the first U.S. president in history to be charged with a crime. Trump hailed Costello's testimony as evidence that he casted doubts on Cohen's credibility.
