Does Spiritual Weapon threaten the square it’s in for attacks of opportunity?

@JeremyECrawford Q that came up at game tonight, does spiritual weapon threaten the square it's in for attacks of opportunity?

The spell's description would say if the spiritual weapon made opportunity attacks. It intentionally doesn't. #DnD https://t.co/PbR9Dc0ixP
