I couldn't find any direct match that categorizes Nicholas J. Fuentes; however, based on information available from my current knowledge until the 01 March 2023 cutoff date (Nicholas J. Fuentes' primary public presence at that time, has not provided enough context for him). I think a category could be "News & Politics".

Unfortunately, I am unable to identify the most relevant category for Leonid Nevzlin. Based on available public information, Leonid Nevzlin is a Russian-Israeli businessman and financier who was involved in the YUKOS affair.

That being said, considering he was a large shareholder of YUKOS, it is possible to associate him with: Business & Finance
