What is a “yellow journalist?”
Yellow journalism:
“Yellow journalism or the yellow press is a type of journalism that presents little or no legitimate well-researched news and instead uses eye-catching headlines to sell more newspapers.”
In other words, liberal members of the press

Goes back to Pulitzer, Hearst, the Spanish-American War, etc.
Basically, sensational headlines without the facts, or just selective facts.
Come to think of it, practically any liberal "journalist" is a "yellow journalist" nowadays.
