Russian Foreign Ministry spokeswoman Maria Zakharova made this statement on Thursday.
DAILY POST reports that Le Pen was after being convicted of embezzlement on Monday.
Reacting, Zakharova said Russia hoped Le Pen would succeed in an appeal against the judgment.
Le Pen is considered the chief political opponent of French President Emmanuel Macron, whom Russia has fiercely criticized over his backing for Ukraine and support for sending European troops there in the event of a peace deal with Moscow.
