I don't know of any specific link, however I haven't looked for one. It wouldn't surprise me. I do know that many Christians have spoken out against Warren. On the other hand, some churches have started groups based on PDL. I equate the sphere of Warren's influence with Oprah's. Oprah is overtly involved with the New Age spiritualism of the global socialist movement.
Be sure to keep me informed if you find anything more on Warren.
