This argument is completely nonsensical, this idea that who revealed the crime matters more than the actual crime.
What does it matter who "influenced" him, if the information was legit? And is it your opinion that none of this information should be released unless it covers all countries equally? Do you honestly think he should have thought, I can't reveal this crime until I find an equal Russian crime, for equality. What a wonderful, open world that would be! Utterly ridiculous.
This is the same stupidity as "Hunter's laptop". It allows the Idiocracy to dismiss anything because "the Russians!".
