Maria Butina sentenced to 18 months in US court. US prosecuted Butina on infiltrating US political groups.
The verdict by a US court sentencing Russian national Maria Butina to 18 months behind bars is an "ugly stain" on the US justice system, the Russian Foreign Ministry said on Friday, TASS reported.
"We consider the decision by a Washington court to sentence Maria Butina to 18 months behind bars as politically motivated," the ministry stressed.
"Our compatriot has been sentenced just for her being a Russian citizen. She has become a victim of tight rivalry between various US political forces and the unbridled anti-Russian campaign in the spirit of McCarthyism," the commentary added.
