  • @Mari-LouA Earlier this week the New York Times' website was using "Whom do the the Shopping Malls of Brazil Belong to" to tease an otherwise well-titled essay. While I understand the grammatical relationships, I did re-read it and ask myself if there shouldn't be some sort of Proximity Rule. – Michael Owen Sartin Jan 19 '14 at 2:48

"And with whom" is correct. Whom is the object of the preposition with.

  • I thought that was correct and that is what I used before I got an answer, but I really appreciate the help. Thank you – Jim T. Jan 19 '14 at 2:56
  • Technically I agree that whom makes sense here. But in spoken day-to-day language, I think the first would be more common. – Noah Jan 19 '14 at 4:52
