Timeline of Brittney Griner's detention in Russia as US secures her release
WNBA star Brittney Griner was released this week in a prisoner exchange with Russia, where she has been detained since Feb. 17 and was sentenced to nine years in Russia prison after she was found guilty of drug charges.
The U.S. classified Griner as "wrongfully detained" in May and has been working for months to secure her freedom.
In an agreement with the U.S., Russia swapped Griner for convicted Russian arms dealer Viktor Bout.
Here's a look back at Griner's trial and major developments in her case:

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.

March 23
Griner meets with U.S. officials for the first time since being held in pre-trial detention in Russia for over a month.

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.

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.

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."

After months of negotiations, the U.S. announced that Griner was released in a prisoner exchange with Russian arms dealer Viktor Bout.
President Biden, joined by Griner's wife at the White House, told reporters that the road to Griner’s release involved "painstaking and intense negotiations" and he thanked those who "worked tirelessly to secure her release."
"She's relieved to finally be heading home and the fact remains that she's lost months of her life, experienced a needless trauma," Biden said. "She deserves space, privacy and time with her loved ones to recover and heal from her time being wrongfully detained."
Griner landed in the United Arab Emirates, which helped facilitate the transfer, Biden said.
Meanwhile, Biden also vowed to "never give up" on securing Whelan's freedom.
“Sadly, for totally illegitimate reasons, Russia is treating Paul's case differently than Brittney’s. And while we have not yet succeeded in securing Paul's release, we are not giving up. We will never give up," he said.
