Step-by-step explanation:
The statement is False. Partisan press refers to a newspaper or other news publication that takes a clear political side or bias, rather than remaining objective. In American history, many newspapers were the voices of political parties and practiced partisan journalism. They printed party propaganda and messages, promoting the interests of the political parties and their policies. Objective reporting, which focuses on simply reporting the facts without any bias, did not become prominent until the early twentieth century.
