Jurors in the New York case have been told that corrupt Turkish officials shut down the investigation and organized a purge of the police and prosecutors who ran it. They were also told that Mr. Zarrab had put up bribe money for judges, “so that everything could be made to go away.”

In Turkey, officials remained defiant over the weekend in their attitude toward the case, which has the country abuzz over the allegations of huge bribes and political influence. In a speech to supporters on Saturday, President Erdogan denounced the United States court and repeated accusations that members of the Fethullah Gulen movement, often referred to as FETO, had fabricated the evidence.

“Fake, unreal courts cannot sentence my country,” he told a local party congress in the eastern city of Kars. “Fake, unreal courts constituted with fictitious representatives of the so-called vile FETO can never sentence my country. We serve, others smear.”

Turkey’s foreign minister, Mevlut Cavusoglu, followed suit, repeating allegations that followers of Mr. Gulen had infiltrated American diplomatic missions in Turkey and even institutions in the United States. “We tell Americans, to their face: We know how FETO infiltrated American institutions and judiciary,” he said at a groundbreaking for a cultural center in Antalya.

The Turkish financial police continued actions to seize the assets of Mr. Zarrab and 22 others connected to him. Turkish newspapers published a list of assets seized from Mr. Zarrab, showing that he owned real estate valued at close to 300 million lira, or about $75 million, and a private jet worth $12 million. Three of his employees were detained and charged with “providing documents” to the United States court.

The conversation in which Mr. Zarrab was quoted saying that one needed to lie to get out of prison took place on Sept. 15, 2016, the summary says. That was six months after his arrest and more than a year before he pleaded guilty.

In their letter to Judge Richard M. Berman, Mr. Atilla’s lawyers said due process required that prosecutors disclose evidence that is exculpatory or could be used to help impeach a government witness “in sufficient time to permit the defendant to make effective use of that information at trial.”
