In theory, this would increase the president's control of the government. The president is the head of the executive branch and so an increase in the size of that branch ought to give the president more control of the government. However, it is not possible to know this for sure because the president has rivals for control of the bureaucracy. Congress has a great deal of power over the bureaucracy as well because it can control the budgets that the agencies work under and it can rewrite the laws that the bureaucracy administers. Therefore, the increasing size of the bureaucracy ought to increase the president's power but will not necessarily do so.
