Who is Wheeler?
He is the private investigator who was hired to work for the Rich family paid for by Butkowski. This is all acknowledged.
Wheeler is also a Fox News contributor, hence the connections with Fox you can hear him talk about in the recording.
Here is a vid of him on Hannity, so you can also hear that his voice matches the one from the secret youtube recording...
