He was born here, I'll give you that. But he moved away and is a dual citizen now. Yes, he's an Irish citizen but seen as a "soup taker" here by some.

I don't understand Ukranian but am told by someone I trust that there are some easily found posts on Ukranian Facebook of him causing significant issues for some Ukrainian journalists.
