After an extensive search - both of my own files and internet search - I am not able to substantiate that information. I suspect I got him confused with another FBI/ DoJ person; the pattern fits a number of them, most prominently Rod Rosenstein.
John Durham is extremely jealous of his personal information and all I can confirm is that he is a good Catholic and a Red Sox fan. I apologize for misleading information - very busy holiday press for me.
Thank you! Yes, Durham is so private. I read when I was looking up info that at one point when he became a practicing attorney at some point, his mother was concerned that he would not be able to make daily Mass any more.
