1) Legislative Branch
The Legislative Branch (aka Congress) consists of 2 chambers: the U.S. Senate with 100 Senators (2 per State) and the U.S. House of Representatives (based on population) --- by law, there are 435 representatives in the House of Representatives --- based on each State's population as a % of the U.S. Population.
The Legislative Branch is responsible for creating laws.
The Constitution does not (in the House of Representatives) allow representation of the District of Columbia or the Territories. Washington D.C. and the Territories of Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands are represented by one non-voting delegate. Puerto Rico elects a resident commissioner; other than having a 4-year term, the resident commissioner's role is identical to delegates from other Territories. The 4 delegates and resident commissioner may participate in debates.

2) Judicial Branch
The Judicial Branch consists of 107 courts known as the Federal Court System. They are responsible for ruling on cases that come to them from lower courts in respect to the validity of relevant laws that the U.S. Congress has passed, as well as the U.S. Constitution and all pertinent earlier court findings.
The 3 levels of the Federal Court System are:
1. Supreme Court
2. Appeals Courts
3. District Courts
The judicial power of the United States shall be vested in one Supreme Court --- this is the only court specifically referenced in the Constitution (Article III, Section 1); and in such inferior courts as the Congress ... shall establish. The number of judges on the Supreme Court is not stated in the Constitution --- however currently there are 9 Federal Judges on the Supreme Court.
"The judicial Power of the United States shall be vested in one supreme Court and in such inferior Courts as the Congress may from time to time ordain and establish." Those inferior courts are:

3) Executive Branch
The Executive Branch is headed by the U.S. President and consists of various other positions that go with the Executive Branch. The lack of specific, detailed language in the U.S. Constitution on such things as "Executive Orders", "Commander in Chief" and the "Pardon" powers, has given the President of the U.S. (POTUS) a great deal of nebulous power and flexibility.
Today, the Executive Branch consists of over 3 million staff; other than the Vice President, all the rest of them are appointed or hired --- many require U.S. Senate confirmation. { PAY ATTENTION: the above mentioned 3 Million staff are NOT ELECTED; in other words, those unelected 3 MILLION STAFF are PRESDENTIAL APPOINTEES, or HIRED by those Appointees!! }
President Trump's Cabinet, top 15 picks plus other key roles, for his Executive Office follow. [Cabinet members are listed in their order in the line of succession to the Presidency after 1) Vice President, 2) Speaker of the House and 3) President Pro Tem of the Senate.
