In their letter, the House members say that the Gosnell and the Planned Parenthood lobbying story “surely … meet your threshold criteria for a national news segment.”

“Yet, despite this obvious fact, coverage of these stories has eluded your news divisions. Our modern world offers no shortage of calamities and crimes to occupy the time of writers, video editors, and announces. Nonetheless, we see no excuse for your failure to report these stories other than blatant media bias,” they wrote, adding that the networks have “betrayed” their viewers and undermined their “credibility in the public square.”

The congressmen added that they would “welcome a response” and explanation as to why these stories do “not merit airtime on your programming.”
