The Supreme Court is America's top court. It will make a big decision. The decision is about babies born in the United States.
Right now, babies born in the US are US citizens. This is an old rule. A past president made a new rule. The new rule says some babies are not citizens. Their parents are not from the US.
Many people say the new rule is wrong. They say the old rule is very important. The Supreme Court will decide. They will say yes to the old rule or yes to the new rule. The decision will come next year. It is a very important decision for many families.
