President Nixon claimed that allowed him to keep phone calls secret

A. Executive privilege
B. Presidential privilege
C. Constitutional privilege
D. Judicial privilege

The answer is executive privilege.  This is when the President and members of the executive branch can defy subpoenas by legislative and judicial branches. Presumption of privilege is use when privilege is qualified.  In Nixon’s case, he only declared a generalized need for privilege but the court believed that the interest of obtaining the truth needed priority.
