A New York judge on Friday delayed Donald J. Trump’s criminal trial in Manhattan until at least mid-April, postponing the only one of Mr. Trump’s four criminal cases that appeared set to begin.

The delay — lasting 30 days from the judge’s Friday decision — stems from the recent disclosure of more than 100,000 pages of records that may have some bearing on the case. Citing the records, Mr. Trump’s lawyers sought a 90-day delay of the trial, while the Manhattan prosecutors that brought the case proposed a postponement of up to 30 days.

The prosecutors from the Manhattan district attorney’s office, who accused the former president of covering up a sex scandal during and after his 2016 campaign, said the extra time would allow Mr. Trump’s lawyers to review the records that recently emerged.

Mr. Trump, who recently clinched the Republican presidential nomination for the third time, was initially set to go on trial on March 25. Now, the judge in the case, Juan M. Merchan, will hold a hearing that day to determine whether the trial should be delayed further — and if so, for how long.

Mr. Trump, who faces four criminal trials and several civil lawsuits, has succeeded in stalling many of his legal entanglements.

A criminal case against Mr. Trump in Washington, where he is accused of plotting to overturn the 2020 election results, was initially supposed to go to trial this month, but that is delayed while Mr. Trump appeals to the Supreme Court.
