Earlier, Zissou said that the protection of the Russian businessman is preparing a lawsuit against the US Bureau of Prisons due to the fact that Bout is not provided with qualified medical care.
The wife of Victor Bout Alla, a prisoner in an American prison, reported a sharp deterioration in his health in an American prison.
In May, the Russian embassy in Washington said that Russian citizens Viktor Bout and Roman Seleznev, held in US prisons, had been denied medical care.
