Congressman Baxter, I know you will want to support our application to clear-cut the old growth timber in the Great Northern forest. After all, surely you don't want the media to find out about that affair you've been having with a certain Capitol Hill intern.

Appeal to force

Explanation:

The statement being made in this passage regarding the scenario is an example of an "Appeal to force" or "Threat of Force". This is when an individual uses a subtle threat when speaking to another individual in order to influence the second party into accepting a specific conclusion to the argument/conversation. Such as in this case, if the second party does not accept the application then Congressman Baxter has made the subtle threat that he will make public the second parties affair.
