My name is Donald Trump. I am the head of the executive branch. The Vice president, myself, and the cabinet make sure laws are carried out, I command the armed forces, and I can veto or reject laws passed by Congress.
I am in Congress. Congress is made up of members of the Senate and House of Representatives. Congress is in charge of the Legislative branch. We make laws, establish taxes, and we can reject vetoes.
I am John Roberts. I am in the Judicial Branch. The Judicial branch is made up of the Supreme Court which has 9 justices. Here in the Judicial branch, we interpret laws, we decide if laws follow the Constitution, and we can overturn the President's actions if these actions go against the Constitution.
