I am reading this 2016 article: EI benefits (The Globe and Mail)
The article is written by the reporter R. Younglai. In an academic paper, I am talking about a specific theory/concept which is mentioned in a number of sources, including the Globe and Mail article.
In the article, R. Younglai quotes a university professor
... blah blah ... "It is sort of ironic. When a big negative shock comes, the unemployment system is not generous enough. When the economy starts improving and the unemployment rate starts going down, it is too generous," said Miles Corak, an economics professor with the University of Ottawa.
In my paper, I am discussing this concept. Who should I cite - the reporter or the professor who gave the quote?
Here is my sentence with the in-text citation:
... blah blah blah concept ... (John 2013; Jack 2015; XXX 2016).
Should I cite as (Corak 2016) or (Younglai 2016)?
Note that I don't want to write "According to the report by Younglai (2016), Miles Corak said ..." because there are many other sources in the same citation parenthesis.
I am following the Chicago Author-Date style. I can't find anything related to this in the guide.
