The article attributes the "too socialist" comment to a "leaked memo", but neither claims that it was leaked specifically to this publication, nor cites another source for it. No other news outlet besides this one has reported this story, and this website appears to lack any particular indications of reliability (e.g., it doesn't have a Wikipedia page). So for now I'm skeptical of the veracity of this story.
