Does Puerto Rico have US Senators or Congressmen?

Answer 1

No, Puerto Rico does not have representation in the US Congress equal to that of a US State. What they have is a single nonvoting Member of Congress called a Resident Commissioner. This Position is filled by election of the voters of Puerto Rico for a term of four years. The current Resident Commissioner is Pedro R. Pierluisi.

Although Puerto Rico had been part of the United States since the end of the Spanish-American War in 1898, the territory had not been designated for ultimate statehood, and Congress could determine which parts of the Constitution would apply. In Balzac v. Porto Rico, 258 U.S. 298 (1922), the Supreme Court of the United States held that certain provisions of the U.S. Constitution did not apply to territories not incorporated into the union. The answer is in the US Constitution itself. The Art. IV, sec 3 declares "The Congress shall have power to dispose of and make all needful rules and regulations respecting the territory or other property belonging to the United States".

Answer 2

As a US Territory, Puerto Rico has a single nonvoting member in the US House called the Resident Commissioner. Only US States have representation in the Upper House as the Senate is called.
