Don't be silly. The President is not responsible for the actions of everyone who works for or in the executive department.
For example my commander, who being part of the military has Obama as his Commander in Chief, recently stole some TVs from the Army and was relieved of command. Do you blame Obama for this? Why not he's the man in charge is he not? Why is he not insuring that a Company Commander is following his own command supply discipline program?
Clearly its not his personal responsibility to behave correctly, nor is it his battalion commander's responsibility, nor is it his brigade commander's, nor is it his division's commander, nor is it his corps' commander, nor is it his component commander, nor is is the responsibility of the Chief of the Army, the Joint Chief, the Secretary of Defense, no CLEARLY its the President's.
That's why there is a chain of command, that's why the different departments have secretaries and multiple levels of organizations.
People love to take Truman's "The buck stops here" desk ordainment and blow it massively out of proportion and pretend it means that one man is responsible for the personal actions of millions of people.
Again, don't be silly.
