Lawyer invited to testify before Trump grand jury

WASHINGTON (AP) — A lawyer who previously advised Michael Cohen, the key government witness in the hush money payment investigation into Donald Trump, has been invited to appear Monday before a Manhattan grand jury that is considering potential charges against the former president, according to a person familiar with the matter.

Robert Costello had advised Cohen before the two had a falling out, and is prepared to offer testimony to the grand jury attacking the credibility of Cohen's statements, according to the person, who insisted on anonymity to discuss secret legal proceedings.

Costello had contacted a lawyer for Trump saying that he had information that contradicted Cohen's current statements and that could be exculpatory for Trump, the person said. The lawyer brought it to the attention of the district attorney's office, which last week subpoenaed Costello's law firm for records and invited him to provide testimony on Monday afternoon.

The Manhattan district attorney's office declined to comment on Sunday. Prosecutors have not said when they expect to conclude their work or when or if Trump might be charged. The former president claimed in a post on Saturday that he would be arrested on Tuesday, though people close to him later said that he had been given no updates from prosecutors.

The New York Times first reported on Costello's expected appearance before the grand jury.

Cohen is a former lawyer and fixer for Trump who has been a key witness in District Attorney Alvin Bragg's investigation, meeting regularly with prosecutors and appearing before the grand jury earlier this month.
