Yes, but if the man with LS is CR, LE not confirming it was him is like closing the barn doors after the horse has bolted. Plenty of articles published indicating CR was with LS that night, and that LS walked CR to his apartment. Also, I don't recall LE having any problem with saying the boyfriend is a POI (even if it was in response to a question).
It's not like they have denied it was him. LE has been consistent in maintaining specific identity vagueness in regards to who she was with on every video they've talked about.
As to confirming the bf as a POI, it was Parker that did so early on, and I believe it to have been a gaffe. When Qualters returned from vacation the next day, he mentioned specifically that there would be no talking about any of the POIs.
