Thank you for the link.
This article is from "The Jerusalem Post - Israel News" which I am sure is non-bias.
If you read the article it says that " Andrew Torba, the CEO of Gab" said this not Mastriano.
The article is about all the things Andrew Torba said. They try to link him to Mastriano by saying, without proof, "reportedly a consultant for state senator Doug Mastriano".
The only thing we know for sure is that Mastriano advertises on GAB, as well as every other social media site.
I would classify this as misinformation since we know for a fact that Mastriano never said this and they didn't present any evidence that Torba is one of his "consultants".
