NEW YORK — New York Judge James Burke on Thursday declined to dismiss sexual assault charges against Harvey Weinstein, rejecting the disgraced Hollywood titan’s push to have his indictment thrown out.

Weinstein’s lawyers argued the case had been “irreparably tainted” by a detective’s alleged coaching of a potential witness and one of the accusers. They also said the grand jury should have been shown friendly emails he exchanged with his two accusers after the alleged attacks.

Burke ruled that Weinstein’s prosecutorial misconduct claims had “no basis” and that prosecutors were under no obligation to give the grand jury evidence favorable to the defense. He denied Weinstein’s demand for a hearing to examine the police investigation and rebuked his lawyers for what he said were “speculative” claims that political pressure had led to the charges.

Weinstein, 66, has denied all allegations of nonconsensual sex. He is free on $1 million bail. His next court appearance is scheduled for March 7.
