Answer:
The Executive, The Judiciary, The legislative
Step-by-step explanation:
Federal government has three parts.
They are the Executive, Legislative (Senate and House of Representatives) and Judicial (Supreme Court and lower Courts). The President administers the Executive Branch of our government.
The Constitution clearly makes the Congress the most powerful of the three branches of government. Depending on the circumstances, however, the President might have more influence on Congress than one would think based on the separation of powers outlined in the Constitution.
