The President apparently believes that his agenda would be impeded by prosecuting past crimes by the bureaucracy and political appointees.

Actually it's more apparent that Trump wants Sessions to go but he believes that his agenda would be impeded by firing the establishment insider, Sessions.

Remember: McConnell arranged to keep the Senate “technically” in session to deny President Trump his Constitutional recess appointment promises, thereby protecting Jeff Sessions.
