Commenting on the case, chairman of the Russian lower house's international affairs committee Leonid Slutsky called it an example of "political inquisition".
"The vaunted American justice in Butina’s case is an example of modern political inquisition. All charges were fabricated, the entire process is clearly politicized, starting with the fact that she was detained on the eve of the meeting of the Russian and US presidents in Helsinki, and it was hardly a coincidence", Slutsky told reporters, adding that Russia should still seek Butina's return from the United States.
The next hearing on the case to take place on 12th of February.
Butina, arrested in mid-July, previously pleaded "not guilty" to charges of acting as a foreign agent and conspiracy to act as an agent of the Russian Federation in the United States. She was residing in the country on a student visa while completing a masters degree in international relations at American University in Washington, DC.
