Donald J. Trump is all but certain to become the first former American president to stand trial on criminal charges after a judge on Monday denied his effort to delay the proceeding and confirmed it would begin next month.
The trial, in which Mr. Trump will be accused of orchestrating the cover-up of a simmering sex scandal surrounding his 2016 presidential campaign, had originally been scheduled to start this week. But the judge, Juan M. Merchan, had pushed the start date to April 15 to allow Mr. Trump’s lawyers to review newly disclosed documents from a related federal investigation.
