Brittney Griner spoke with a media member on Tuesday for the first time since she was arrested back in February in Russia ... saying she had "no complaints" about her detention and adding that she wanted to wish her wife "good luck on the bar exam."
Griner -- who was back in court Tuesday for yet another hearing in her drug case -- spoke with an ABC News producer from behind bars inside the Moscow courtroom.
The outlet recorded the conversation, and in the audio, you can hear Griner calmly send the message to Cherelle Griner (who's been studying to become a lawyer) -- while adding she's "just waiting patiently" for a resolution in her drug case.
