Explain Squealer’s role as a character in the book

Squealer is “a brilliant talker” who is talented in the art of argument. The other pigs say Squealer “could turn black into white” (35). Under Napoleon’s rule, Squealer acts as the liaison to the other animals. He lies to them, rewriting history and reading them encouraging, but false, statistics. Squealer is especially good at playing on the animals’ ignorance and gullibility. He represents the propaganda machine of a totalitarian government.
