...it was nicknamed the Clinton News Network in 2016 because of how partisan it gets.

By anyone. Any "news" network that's on TV is rubbish. It's not like there's a certification or anything.

Anyone who mocks Fox news and then turns around and watches cnn, msnbc, etc, is a fool.

Rush Limbaugh coined that term in 1993 in his book (or perhaps earlier), it wasn't a 2016 invention.

They’re pretty close, especially in regard to Trump himself. For whatever reason his existence turned up partisanship to 11, on both sides.
