On March 10, 2020, an Anti-Corruption Foundation investigation revealed embezzlement of the state budget of Russia and various corruption schemes associated with the television program "The International Sawmill" (ru.

In several of the program’s episodes, Keosayan insults and slanders leaders of various countries such as France, the United States, and Turkey. Emmanuel Macron is frequently incorrectly described, using vulgarities, as a homosexual. And obeying the "personality cult of Putin," the president of Russia is exalted.
