Sessions under oath said that he was recusing himself from all matters connected to Hillary.
So it's not that Sessions is "silent". He wasn't silent. He said he wasn't going to do anything connected to Hillary. And he said it under oath, under penalty of perjury.
“Sessions under oath said that he was recusing himself from all matters connected to Hillary.”
Not all the investigations are connected to Hillary. So this entire complaint about his recusal which is proper btw, is besides the point.
The investigations loom larger and are beyond Hillary.
