Sure, but if documents supposedly belonging to French political actors have Russian names in the metadata, it means they were tampered with. It doesn't matter if the tampering was done by Russia or by the USA; either way, those documents are not authentic, which means the whole "look what we found when we hacked his email" story is a fraud.
