The American Civil Liberties Union (ACLU) and the National Security Agency (NSA) are two different organizations that have very different goals. The ACLU is an organization that fights to protect civil liberties, like freedom of speech and the right to privacy. The NSA is an organization that works to collect information about people for the purpose of national security. The ACLU and the NSA don't agree about how much information someone should have to share with the government. The ACLU believes that people should only have to share the necessary amount of information for the safety of the country. The NSA believes that it should be able to collect a lot of data about people, which the ACLU worries can be a violation of people's privacy. Both organizations are working to protect our country, but they have different ways of looking at it.
