The President and the congress
A bureaucratic drift is a kind of theory that tells about the tendency of bureaucratic agencies to create new policy that comes from the original mandate. It produced legislation that come from elected officials.
The president has the ability to check the power of the bureaucracy. He does this by vetoing bills that have made it through congress if he disagrees with them. This keeps congress from passing laws unchecked.

Congress
The structure of the federal bureaucracy contributes to bureaucratic independence by enabling agencies created by Congress to operate outside the cabinet structure. With congressional funding and contributions agencies are helped from the beginning with a boost that enables them to later stand on their own.
When policy is implemented, due to the discretion of agencies in the implementation of policy, it can slip away from what voter's might want in the direction of what the bureaucracy wants (to an extent). This movement of policy in the direction of the bureaucracy's discretion is called "bureaucratic drift".
