NEW YORK — The Manhattan grand jury hearing evidence in the criminal investigation of Donald Trump’s alleged role in a scheme to pay hush money to a porn star won’t meet Wednesday as regularly scheduled, according to two people familiar with the matter.

The reason for the adjournment wasn’t immediately clear. The grand jury typically meets Mondays, Wednesdays and Thursdays, one of the people familiar with the matter said, and it heard from witnesses earlier this week.

“The grand jury has been told to stay home today. They’re on standby for tomorrow,” one senior law-enforcement official said.

“The D.A.’s office didn’t tell the court why the day off, [they] just said, ‘I don’t want them today, maybe tomorrow,’” the official added.

A spokesperson for Manhattan District Attorney Alvin Bragg didn’t respond to a request for comment.

The investigation appeared to be in its final stages in recent days, as prosecutors allowed a defense witness, Robert Costello, to testify on Monday.
