Why did the US government set up the committee on public information

The Committee on Public Information was formed to create a propaganda campaign to try to get more people to enlist in the army during World War 1.

Explanation:

This committee was established in 1917 and used until 1919, with the end of the war. Roughly 75,000 volunteers were used. They could create posters and flyers and even published their newspaper known as the Official Bulletin. They would spread success stories that would encourage men to sign up to fight oversees and for people to donate money to the war efforts.
