Does the POTUS have an obligation to weigh in on Comey-gate or would that be inappropriate?

6. I believe that the Director of the FBI reports to the Director of National Intelligence

"Along with the Deputy Director, the Director ensures cases and operations are handled correctly. The Director also is in charge of staffing the leadership in any one of the FBI field offices with qualified agents. The Director briefed the president on any issues that arose from within the FBI until the Intelligence Reform and Terrorism Prevention Act of 2004 was enacted in response to the September 11 attacks. Since then, the director reports to the Director of National Intelligence, who in turn reports to the President."

The reporting structure for Comey report is that he reports to John Crapper who then reports to President Obama.

The Director of the FBI is appointed by the President but must be approved by the Senate.
