Fake news often happens when someone is not satisfied with something and makes a lie for example, when one of our presidents was elected tones of false allegations popped up because some people wanted our president out.
Fake news is all around the world trying to spread lies about people like the president, and high raked people in society. They like to give false information about people. For example, during the election, people decided to mix things around and mess up the voting counts. So now they are having to recount them :(
