For days, CNS refused to mention the story of Donald Trump's attacks on Khizr Khan, father of a deceased American soldier who spoke at the Democratic National Convention, on its front page -- no mention of the attacks or the bipartisan criticism of them. CNS did enter a few Associated Press articles on the controversy into its website, but they never appeared on the front page. Given that it's highly unlikely that most CNS readers venture beyond the front page, that means CNS effectively censored the story.
It was only when President Obama commented on the controversy in a way it disapproved of that CNS deemed the story worthy of its front page - and even then, Trump's attacks were not the focus of the story.
Note the framing used by Melanie Hunter in her Aug. 2 CNS article, under the headline "In Front of Foreign Leader, Obama Denounces Trump as ‘Unfit to Serve’":
During a joint White House press conference with Singapore Prime Minister Lee Hsien Loong, President Barack Obama spent more than five minutes explaining why he thinks GOP presidential nominee Donald Trump is “unfit to serve as president,” pointing to recent statements Trump made about the parents of Capt. Humayun Khan, a decorated Army veteran who was killed in Iraq.
Thus, CNS makes the issue not Trump's attacks on the parents of a dead U.S. soldier but Obama criticizing the attacks in front of a "foreign leader."
While Hunter went on to summarize the back-and-forth between Trump and Khan, she failed to report that Trump's (and, presumably, Hunter's) fellow Republicans have criticized Trump's attacks -- something she knows exists because she linked to an AP article documenting that criticism.
Hunter's bias and incomplete reporting would seem to be yet another violation of CNS' mission statement, which claims that it "endeavors to fairly present all legitimate sides of a story."
