Okay, so imagine the United States is like a big school with lots of students. The students need someone to help make rules and important decisions for the school, like what games to play at recess and how to spend money on new books for the library. This person is called the president. Donald Trump was the 45th president of the United States, which means he was like the boss of the school for a while.
Donald Trump used to be a businessman, which is like someone who runs their own lemonade stand or sells cool toys to other kids at school. But then he decided to run for president and he won. Some people liked the things he wanted to do, like making the school's lunch tastier, while other people didn't agree with him and thought he was doing the wrong things.
When he was the president, Donald Trump made a lot of changes to the rules of the school, called laws. They were about things like how people can come into the school from other countries, and how much money the school should spend on new books. Some people thought the changes were good, while others said they were not fair.
After a while, another student ran for president, and he won, so now he's in charge. It's like when a new kid becomes the captain of the soccer team and has different ideas for how to play the game. So, Donald Trump isn't the president anymore, but he's still important because he's always talking about what he thinks should happen at the school, just like other grown-ups who used to be in charge.
It's important to understand that people have different ideas about Donald Trump, just like kids at school might have different ideas about the best game to play at recess. Some kids might like dodgeball while others prefer kickball, and that's okay. It's the same with adults and their thoughts about Donald Trump.
