Reza Zarrab, a Turkish-Iranian gold trader who had agreed to cooperate with prosecutors to not stand trial in the United States over a breach of now-lifted U.S. sanctions on Iran, money laundering and other charges, confirmed the defense's claim late Tuesday, stating that he "did say that lying was the fastest method" to get out of a U.S. prison.

Zarrab, who pleaded guilty to his charges, is currently testifying as a witness in the trial of Atilla, the deputy CEO of state-owned Halkbank. Meanwhile Atilla, who was arrested while in the U.S. in March 2017, has pleaded not guilty to the charges of conspiring with Zarrab.

"Reza Zarrab supposedly said in a 9/2016 jailhouse call that he needed to lie 'in order to get out or to get a reduced sentence,' according to the defense letter. Mehmet Hakan Atilla's team says that shows Zarrab's 'willingness to fabricate testimony out of whole cloth,'" courthouse reporter Pete Brush detailed.

The reporter also said that Atilla's team says the information suggests the prosecution violated judge Richard Berman's Nov. 28 order for the U.S. to turn over all exculpatory material and that "the failure should be deemed a violation of Atilla's right to due process."

Defense attorney Victor Rocco also raised questions over Zarrab's credibility in his opening statement, saying the case was really about Zarrab's crimes.

He said Zarrab made a deal to get out of jail free, possibly joining the U.S. witness protection program so he and his family can live in the United States.

Speaking at the Justice and Development Party's (AK Party) group meeting, President Recep Tayyip Erdoğan said the ongoing Zarrab case in the U.S. was a similar attempt to the one in Turkey that took place on Dec. 17 and Dec. 25, 2013, which has been called the Gülenist judicial coup attempt. "There is no corruption investigation or corruption case, as claimed by some circles under the guidance of the Gülenist Terror Group [FETÖ] and the main opposition. Such a claim is not the point in question and cannot be at the core of the case in the United States," the president said.

Stressing that the Dec. 17 and Dec. 25 judicial coup attempt was aimed at obliterating the constitutional order, Erdoğan said the Zarrab case has the same goal in the international arena. "

The conspiracy claims in the indictment of the case are true. But this conspiracy is not against the United States, it is a conspiracy against Turkey," he said.

Erdoğan also asserted that the case is trying to victimize Turkey on the grounds that it violated sanctions.

Directing his words at the U.S., the president asked whether Washington has yet to grasp the July 15 coup attempt. "I address America from here: Have you not been able to grasp the July 15 FETÖ coup attempt, will you not?"

On July 15, 2016, a small military junta linked to the FETÖ attempted to topple the democratically elected president and the government of Turkey. The attempt was prevented by troops loyal to the government, along with police and millions of people in favor of democracy. Putschist soldiers killed 249 people, mostly civilians, and injured over 2,000 people.

Bloomberg news has also echoed the same narrative, saying the Zarrab trial adds to a growing narrative that the West is plotting against Turkey.
