ELI5: Explain Like I'm 5

President pro tempore emeritus of the United States Senate

Okay kiddo, so you know how the United States has three branches of government - the executive, legislative, and judicial branches? The legislative branch is in charge of making laws and is divided into two parts - the House of Representatives and the Senate.

The Senate is made up of 100 people, called Senators, and they make decisions by voting on things. But just like in school, they need someone in charge to make sure everything runs smoothly. The person in charge of the Senate is called the President of the Senate, but that's actually the Vice President of the United States. However, the Vice President doesn't always have time to be at the Senate because they have other important things to do, like helping the President run the country.

That's where the President pro tempore of the Senate comes in. They are sort of like the Vice President of the Senate when the Vice President is not there. They are elected by the Senators and they help make sure that everything runs smoothly in the Senate. They also have some important duties like signing bills and making sure the Senate is following the rules.

Now, the "emeritus" part of the title you asked about is a fancy word that means honorary or retired. So, the President pro tempore emeritus of the Senate is someone who used to be the President pro tempore of the Senate and did a really good job, so they were given an honorary title. They don't have any real power or duties anymore, but they are respected because they did an important job in the past.
