Anastasia Vashukevich, better known by her pen name Nastya Rybka, has been detained in Thailand since February when police raided a risque seminar in the seaside resort city of Pattaya.
Vashukevich had travelled to Thailand after becoming embroiled in a political scandal with Russian aluminium tycoon Oleg Deripaska, a onetime associate of Trump's now-disgraced former campaign director Paul Manafort.
