Trump must simply say no on any special prosecutors. This would spell the end of any more agenda items being considered or passed.
It ruined Nixon’s plans, Reagan’s after Iran-Contra, Clinton, and W Bush (all efforts were diverted to keeping Rove out of jail).
They know this is the only way to slow or stop Trump.
Sessions has to pass the word as No. And Donald better not ever mention “tapes” again
Only exception I would make is if you took a guy like asst.AG Rod Rosenstein and told him to do anything he needed as long as he finished up in three weeks and got the job done once and for all.
