The surprise final witness provides an updated clue to the timing of a possible indictment of Trump and of any co-defendants.
The grand jury, which meets in secret in a lower Manhattan office building, only gathers to hear testimony during three-hour afternoon sessions on Mondays, Wednesdays, and Fridays.

A Manhattan grand jury that is expected to vote soon on whether to indict Donald J. Trump may hear testimony Monday attacking the prosecution’s star witness, according to people with knowledge of the matter.
The testimony would come from a lawyer, Robert J. Costello, who would appear at the request of Mr. Trump’s lawyers, the people said. Mr. Costello was once a legal adviser to Michael D. Cohen, Mr. Trump’s former fixer, who has been a key witness for the Manhattan district attorney’s office.
Mr. Costello and Mr. Cohen had a falling out, and Mr. Costello would appear solely to undermine Mr. Cohen’s credibility, the people said.
Under New York law, a person who is expected to be indicted can request that a witness appear on his or her behalf. Mr. Trump’s lawyers have asked that Mr. Costello testify, but the final decision rests with the grand jury; it is unclear whether they have made a decision. The grand jury has been hearing evidence about the former president’s involvement in a hush money payment to a porn star.
Mr. Costello’s appearance would come soon after Mr. Cohen concluded his own grand jury testimony. If Mr. Costello testifies, there is also a chance that Mr. Cohen will be asked to return to rebut some of Mr. Costello’s assertions. [Continue reading…]
