WNBA star Brittney Griner, who has been detained in Russia for over five months, was found guilty on drug charges in a Moscow-area court Thursday. She was sentenced to nine years in prison.
As the U.S. floats a proposal to negotiate her release, here's a look back at major developments since she was detained in Russia more than five months ago.
Brittney Griner timeline:
Griner, a 31-year-old Houston native and professional basketball player for the WNBA's Phoenix Mercury, is detained at Sheremetyevo International Airport in Khimki as she returns to Russia to play during the WNBA's off-season. She is accused of having vape cartridges containing hashish oil, which is illegal in the country.
Russia invades Ukraine, unleashing airstrikes on cities and military bases.
After imposing a wave of new sanctions against Russia, President Joe Biden labels Russian President Vladimir Putin a "war criminal" during a press conference at the White House amid a State Department review of whether the U.S. considers Russia's attacks on Ukrainian civilians a war crime.
Concerns in the U.S. over the well-being of Brittney Griner grow as Russia extends the pre-trial detention of the WNBA star until May 19. The extension of Griner's detention comes during a volatile time for U.S.-Russian relations as Russian President Vladimir Putin escalates attacks on Ukraine.
The U.S. State Department issues a statement demanding access to Griner. "We are closely engaged on this case and in frequent contact with Brittney Griner's legal team. We insist the Russian government provide consular access to all U.S. citizen detainees in Russia, including those in pre-trial detention, as Brittney Griner is," it says.
Griner meets with U.S. officials for the first time since being held in pre-trial detention in Russia for over a month.
"The consular officer who visited with Brittney Griner was able to verify that she is doing as well as can be expected under these very difficult circumstances," State Department spokesman Ned Price tells reporters.
Griner's meeting comes as Secretary of State Antony Blinken announces that the State Department has made a formal assessment that Russian forces have committed war crimes in Ukraine.
"Based on information currently available, the U.S. government assesses that members of Russia's forces have committed war crimes in Ukraine. Our assessment is based on a careful review of available information from public and intelligence sources," Blinken said in a statement.
Calls to free Griner and other Americans detained in Russia escalate following the release of U.S. Marine veteran Trevor Reed on April 27, who was freed from a Russian prison as part of a prisoner exchange. Former Marine Paul Whelan has also been detained in Russia since 2019.
The U.S. State Department announces that the U.S. government has classified Griner's case as "wrongfully detained" in Russia. With this classification, the U.S. becomes more involved in negotiating for her freedom as opposed to waiting for her case to play out in the Russian legal system.
The WNBA honors Griner with a floor decal bearing her initials and jersey number (42) on the sideline of all 12 WNBA teams as the 2022 season kicked off.
Russia extends Griner's pre-trial detention until June 18 as the U.S. works to secure her release.
Griner's wife, Cherelle Griner, speaks with "Good Morning America" co-anchor Robin Roberts about her wife's detention and urges President Joe Biden to do everything he can to bring her home.
Cherelle Griner says that her wife texted her when she was first taken into custody, but Brittney's phone is taken soon after.
She says she is "grateful" for a call from Secretary of State Antony Blinken, but adds that she would also like to also speak with Biden.
"I just keep hearing that, you know, he has the power. She's a political pawn," she said. "So if they're holding her because they want you to do something, then I want you to do it."
As the Boston Celtics and Golden State Warriors prepare to face off in the 2022 NBA finals, players call attention to Griner's case.
"She needs to be home, she needs to be safe, she needs to be with her family," Warriors point guard Steph Curry tells ESPN.
A Russian court extends Griner's pre-trial detention for a third time, and says that she will remain in custody until July 2.
Cherelle Griner tells The Associated Press that she has lost "trust" in the U.S. government after a planned anniversary call between the couple didn't take place because the embassy line wasn't staffed over the weekend.
"I was distraught. I was hurt. I was done, fed up," Cherelle Griner said.
"We deeply regret that Brittney Griner was unable to speak with her wife because of a logistical error," a State Department spokesperson told ABC News, adding that the call will be rescheduled for a later date.
Griner attends a preliminary hearing as her detention is extended for the fourth time and the first day of her trial is set for July 1.
Friends and family members of Griner gather for a vigil outside the Russian Consulate in New York City, as pressure mounts on the U.S. to secure the release of the WNBA star.
Griner personally reaches out to President Biden, urging him to help get her out of Russian custody, in a handwritten letter delivered to the president on the 4th of July. "As I sit here in a Russian prison, alone with my thoughts and without the protection of my wife, family, friends, Olympic jersey, or any accomplishments, I'm terrified I might be here forever," Griner wrote to the president.
White House press secretary Karine Jean-Pierre tells reporters during a briefing that Biden read Griner's handwritten letter and her case is a "top priority" for the president.
Biden and Vice President Kamala Harris calls Cherelle Griner to "reassure" her that they are working to secure her wife's release, the White House announced.
Griner pleads guilty on drug charges, saying that the vape cartridges containing hashish oil were in her luggage unintentionally. She said that she had "no intention" of breaking Russian law and packed the cartridges by accident.
During the hearing, U.S. officials who attended the trial delivered a response letter to Griner from Biden, the State Department said.
Cherelle Griner speaks out at a press conference, saying that she read the letter Biden wrote to her wife and it brought both of them "so much joy.""I believe every word that she said to him, he understood and he sees her as a person," Cherelle Griner said. "And he has not forgotten her, which was her biggest cry in her letter."
Character witnesses take the stand in Griner's trial as the U.S works to secure her release.
Griner appears for the fourth day of her trial, where her attorney presents a letter from an American doctor giving Griner permission to use cannabis to reduce chronic pain. Griner is expected to testify but her testimony is delayed.
Griner returns to court, where she speaks briefly with ABC News and shares a message for her wife, Cherelle, who recently graduated from law school. "Good luck on the bar exam," Griner said.
Griner testifies in court, saying she did not mean to leave the vape cartridges in her bag, but that she was in a hurry and was stressed after recovering from COVID-19 that month. She adds that she had permission to use medical cannabis and used a certificate to buy it in the U.S.
In a sharp reversal, Secretary of State Antony Blinken announced later that day that he will hold a call with Russian Foreign Minister Sergey Lavrov "in the coming days" to discuss securing Griner and Whelan's freedom.
"We put a substantial proposal on the table weeks ago to facilitate their release," he said.
Blinken tells reporters that he had a "frank and direct conversation" with Lavrov about a U.S. proposal to exchange convicted arms dealer Viktor Bout in return for Griner and Whelan's freedom."I pressed the Kremlin to accept the substantial proposal that we put forth on the release of Paul Whelan and Brittney Griner," Blinken said. "I'm not going to characterize his responses and I can't give you an assessment of whether I think things are more or less likely, but it was important that [he] hear directly from me on that."
Griner is found guilty on drug charges and sentenced to nine years in prison as her trial came to an end.
Griner's attorneys, Marina Blagovolina and Alexander Boykov, told reporters outside of the courthouse in Moscow on Thursday that they plan to file an appeal.
Biden slammed Russia in a statement and called on Russia to "release her immediately."
"My administration will continue to work tirelessly and pursue every possible avenue to bring Brittney and Paul Whelan home safely as soon as possible," he said.
