Her lawyer, Alexander Boykov, previously told CNN the hearing would occur behind closed doors at the Khimki court, just outside Moscow.
Griner, 31, a Phoenix Mercury player who plays in Russia during the WNBA’s offseason, was arrested February 17. Russian authorities claimed she had cannabis oil in her luggage and accused her of smuggling significant amounts of a narcotic substance, an offense punishable by up to 10 years in prison.
Griner’s detention, which has been repeatedly extended, has sparked a wave of support among dozens of organizations in the US that have joined Cherelle Griner, Brittney Griner’s wife, in urging President Joe Biden to strike an exchange deal with Russian authorities to release Griner and bring her home safely as soon as possible.
More than 40 organizations — including the National Association for the Advancement of Colored People, Human Rights Campaign, GLAAD, the National Urban League and the Women’s National Basketball Players Association — signed a letter to President Biden and Vice President Kamala Harris calling for action to get Griner released.
US Secretary of State Antony Blinken spoke to Cherelle Griner one-on-one last Wednesday, according to a senior State Department official. And US national security adviser Jake Sullivan told reporters aboard Air Force One on Tuesday he and Blinken spoke with Cherelle “in the last few days … to convey that we just can’t even begin to imagine what the family must be going through” and what “Brittney must be going through.”
Cherelle Griner said last week she hasn’t talked to her wife since February 17.
“That includes Paul Whelan, that includes Brittney Griner, that includes people in a number of other countries,” he added. Whelan is a US citizen who was detained in Moscow in 2018 and arrested on espionage charges. He has denied the charges.
“I can’t comment in any detail on what we’re doing, except to say this is an absolute priority,” Blinken said.
“The negotiation for her immediate release regardless of the legal proceedings should remain a top priority,” Lindsay Kagawa Colas wrote, “and we expect @POTUS and @VP to do everything in their power, right now, to get a deal done to bring her home.”
The US Embassy in Moscow will send a US diplomat to Brittney Griner’s hearing on Friday, a US official told CNN.
A State Department spokesperson reiterated that the Griner is “wrongfully detained,” and said that support for her and her family will continue. “The US government will continue to provide appropriate support to Ms. Griner and her family. We will continue to press for her release.”
Griner was named an honorary WNBA All-Star Game starter last week, with the All-Star Game scheduled to take place on July 10 in Chicago.
Griner’s detention abroad is still “tough on our team,” Phoenix Mercury head coach Vanessa Nygaard told reporters before the team’s game Monday against the Indiana Fever.
She expressed hope Griner will return home soon and that President Joe Biden will “take the steps to ensure that she comes home.”
