In Chapter 3, how does BR try to undermine Naylor?

In Chapter 3, Nick Naylor receives word that Oprah wants him on her show on Monday to discuss the surgeon general's call for a tobacco ad ban. Nick calls Jeannette to inform her he will be out of town, and a moment later BR calls him. BR suggests that perhaps Jeannette should go in Nick's place, but Nick convinces him against that.
