What is a propaganda? what group was in charge of it in america?

Propaganda is biased/misleading information, usually to promote/publicize something political.

There was no specific "group" in charge of propaganda in America, but it was definitely used in World War l and ll.

One of the most famous propaganda's, though, is Paul Revere's exaggeration of the Boston Massacre.
