WNBA star Brittney Griner has been released from custody in Russia and is on her way back to the U.S. after a monthslong imprisonment on drug charges, President Joe Biden said Thursday.

She is safe. She is on a plane. She is on her way home, Biden tweeted along with a photo of him embracing Griners wife, Cherelle Griner, in the White House Oval Office.

The two-time Olympic gold medalist was freed in a prisoner swap for international arms dealer Viktor Bout , CBS News and other outlets reported, citing U.S. officials.

We never stopped pushing for her release. It took painstaking and intense negotiations, Biden said at news conference alongside Griners wife, Vice President Kamala Harris and Secretary of State Antony Blinken .

Biden thanked those involved in the negotiations and also the United Arab Emirates, where the prisoner swap took place. He described the past few months as hell for Griner and her wife, but noted Griner is in good spirits, relieved to finally be heading home after experiencing needless trauma.

Griner, 32, was detained in February at Moscows Sheremetyevo Airport after police said they found vape canisters containing cannabis oil in her luggage. Griner admitted that she had the canisters, but said that they were unintentionally packed and that she had no criminal intent.
