Testimony of a key witness in the civil fraud case brought by New York’s attorney general, Letitia James, against President Trump may complicate the judge’s decision, according to an email from the judge made public on Tuesday. At a minimum, the controversy swirling around the longtime chief financial officer of the Trump Organization, Allen Weisselberg, will delay the judge’s decision in the case, which had been expected any day.

“I do not want to ignore anything in a case of this magnitude,” the judge, Arthur Engoron, said in the email to all attorneys, defense and state, alerting them that the level of importance of the issue was “high.”
