Who is in charge of the executive branch of the federal government?

The President is in charge of the executive branch of the federal government, serving as the head of state and head of government. This role includes the responsibility to enforce laws, lead the military, conduct foreign policy, and oversee the federal administration. The President's authority extends to appointing heads of various departments, including cabinet members, who assist in managing these responsibilities.

While the Vice President plays a significant role, primarily in support of the President and stepping in if necessary, they do not oversee the executive branch. The Secretary of State is responsible for foreign affairs but is just one part of the broader executive framework. The Supreme Court, on the other hand, is part of the judicial branch, which interprets laws rather than enforces them. Thus, the position of the President is central and pivotal in maintaining the functions and responsibilities of the executive branch.
