Forget the kindly image of “Uncle Walter,” the most trusted man in America. Even a liberal Newsweek scribe such as Howard Kurtz notes in his review of a new Walter Cronkite biography that Cronkite’s liberal bias blatantly violated basic journalistic standards.

In reading this first major biography of Cronkite, I came to realize that the man who once dominated television journalism was more complicated—and occasionally more unethical—than the legend that surrounds him. Had Cronkite engaged in some of the same questionable conduct today—he secretly bugged a committee room at the 1952 GOP convention—he would have been bashed by the blogs, pilloried by the pundits, and quite possibly ousted by his employer. That he endured and prospered, essentially unscathed, until his death in 2009 reminded me of how impervious the monopoly media were in those days, largely shielded from the scrutiny they inflicted on everyone else. …

… [In 1968}, after Cronkite had belatedly turned against LBJ’s Vietnam War, he met privately with Robert Kennedy. “You must announce your intention to run against Johnson, to show people there will be a way out of this terrible war,” he said in Kennedy’s Senate office. Soon afterward, Cronkite got an exclusive interview in which Kennedy left the door open for a possible run—the very candidacy that the anchor had urged him to undertake. (Kennedy announced three days later.) I am shaking my head at the spectacle of a network anchor secretly urging a politician to mount a White House campaign—and then interviewing him about that very question. This was duplicitous, a major breach of trust. …

… In what would likely be deemed a firing offense today, Cronkite blatantly manipulated an interview with LBJ shortly before Johnson died. According to Brinkley, his producer spliced the footage in unflattering ways, reshooting Cronkite asking the questions so it appeared that he was nodding or raising his eyebrows in disgust when Johnson talked about Vietnam. LBJ saw a rough cut and pronounced it “dirty pool”; I would call it a video version of lying. Under pressure from the former president’s team, CBS undid the misleading editing, so the public never learned of the deception.

At least today’s ideological media don’t try to hide their biases behind a false front of objectivity.
