MOSCOW (AP) β American basketball star Brittney Griner has gone on trial in a Russian court on charges of possessing cannabis oil. Griner was arrested in February at a Moscow airport while traveling to play for a Russian team. The Phoenix Mercury center and two-time U.S. Olympic gold medalist could face up to 10 years in prison if convicted. The next session was set for July 7. A U.S. Embassy official who was in court said she spoke with Griner, who βis doing as well as can be expected in these difficult circumstances.β Her case comes at an extraordinarily low point in Moscow-Washington relations. Griner was arrested less than a week before Russia sent troops into Ukraine, which aggravated already high tensions.
