Answer:
Seek support for policies.
Step-by-step explanation:
The U.S. Cabinet is not part of the legislative branch, therefore it cannot create legislation, it is composed by the heads of departments from the Executive Branch (e.g. State; Foreign Affairs; Treasury; Defense; War Department; Justice or Agriculture).
The Cabinet is an advisory body, appointed by the President, in some countries these function is represented by the Ministers, it is like a “privy council” which do not have the task to spread the word about any policies, this is delegated to the press body.
The Cabinet does not have a specific agenda for meetings, they can occur when the President requires it. The main function of the Cabinet is to support the President and his policies, advising and implementing them. Then the purpose of a Cabinet meeting called by the President calls is to seek support for policies.
