Farther back. When they branded the work of the HCUA "HUAC" and called it "McCarthyism" (when the investigations of Soviet influence began decades prior) and denied the existence of domestic agents allied with Stalin and denied the existence of gulags and denied the existence of Communist sympathizers within the FDR administration and the State Department...
They did not just tell lies of omission. They told outright lies.
General Eisenhower then outlined the entire invasion. When he concluded, he said: "Gentlemen, you now know the entire plan. If any of this gets out, it will be a blood bath on the beaches in Sicily. And we will know where the leak came from--"
Then he left the room. From that time on, no more mention was made of the invasion plans.
Now, those were true American journalists! Not the gang... of leftists, communists, socialists and ignoramuses we have today at CBS, NBC, ABC, NYT, WaPo, CNN, etc
See my home page. The perfidy of the NYT has been recognized by honest people for awhile.
