“From Venezuela, we express our firm opposition to the constant media and political persecution suffered by Vice President Cristina Fernandez de Kirchner,” RIA Novosti quoted Maduro as saying on Twitter.
He noted that sooner or later "truth will prevail."
Earlier, the court sentenced Christina Kirchner to six years in prison in a corruption case.
She and her accomplices are accused of embezzling public money that was allocated for infrastructure projects in the province of Santa Cruz.
