According to Interfax, in this way the court rejected the appeal of the defense against the decision of the Pervomaysky District Court, which in early June placed Pivovarov in a pre-trial detention center until July 31.
According to the investigator, the basis of the criminal case is a post on the Internet with "campaigning to collect funds for the press" for one of the projects.
Pivovarov himself denies the accusations.
His arrest at the Pulkovo airport in St. Petersburg became known on May 31.
The Kremlin, commenting on the situation, stated that the claims of law enforcement agencies to politics have nothing to do with it.
