However, if Sessions is replaced before Mueller issues his report, Mueller will immediately report to the new Attorney General, who will not be recused as Sessions was. Rosenstein loses his acting authority, and the new Attorney General can immediately change Mueller's charter, and control what happens to any report Mueller may produce.
If Mueller leaks the report on his own, his pal Rosenstein won't be in a position to have his back covered.

Wish it would go down that way, but it will not.
Trumps new pick would either be denied outright, or the pass/fail test will be to give our anti-American legislative branch what they want.
Additionally, the DoJ is lawfully subject to Congress. All the document stonewalling conservatives have lived through over the past couple of years, will suddenly stop, and we will see the leftists in Congress get the lawlessly fabricated docs they need to try and take out Trump right away.
