Okay kiddo, so the United States Senate is like a big group where people from each state get together to make important decisions for the whole country. Right now, there are 100 members in the Senate, kind of like there are 100 pieces in a puzzle.
Each state gets to choose two people to be in the Senate, kind of like how in a game of tag, each team gets to choose two people to be "it". These people are called senators, and they work at the Capitol building in Washington D.C.
Senators have a very important job because they help make laws that affect everyone in the country. They vote on things like how much money to spend on schools, what kind of healthcare people should have, and what countries we should be friends with.
Each senator is elected by the people in their state, which means the people who live there get to choose who they want to represent them. Some senators have been there for a long time, but others are just starting out.
That's it in a nutshell, kiddo. Senators are people who make important decisions for our country, and each state gets to choose two of them to represent them.
