MOSCOW (AP) — WNBA star Brittney Griner pleaded guilty to drug possession charges on the second day of her trial in a Russian court in a case that could see her sentenced to up to 10 years in prison. Her abrupt guilty plea came amid a growing chorus of calls for Washington to do more to secure her freedom nearly five months after her arrest amid rising tensions between the U.S. and Russia over Ukraine. A senior Russian diplomat said earlier that no action could be taken by Moscow on Griner until the trial was over. Griner was detained at a Moscow airport while returning to play basketball in Russia. Police said they found vape canisters containing cannabis oil in her luggage.
