Sunday morning, the Republican chairman of the Senate health committee — a physician — went on TV and called the president's new vaccine order "wrong on so many levels." Not a Democrat. Not a blue-state health official. Bill Cassidy, the GOP's highest-ranking health voice, doing the math out loud on CNN: splitting the MMR vaccine into separate shots means parents go to the doctor "six times" instead of twice, miss work six times, and — his words — "the president's proposal is going to end up with more children being sick." * That's a five-alarm story for any newsroom: the party's own doctor-in-chief breaking with the president on the policy of the week. So what did Fox's politics feed serve its readers on the same Sunday? "Sen Johnson releases new Fauci text flagging COVID vaccine concerns during pregnancy." And, in case one Fauci wasn't enough: "Fauci refuses Senate appearance after invoking Fifth Amendment more than 100 times in COVID probe." As of Sunday evening, a search of Fox's site and its politics feed turns up no story on Cassidy's remarks at all. The senator got three quotes deep into criticizing a sitting Republican president's health order, and Fox's vaccine coverage of the day was two stories about a man who left government in 2022. * This is the quietest trick in the agenda-setting playbook, and it doesn't require writing a single misleading word. You just change the subject. Vaccine news day? Absolutely — here's some vaccine news from 2021. It's the newsroom equivalent of your mate answering "how did your exam go" with a story about a test he passed four years ago. * It lands harder when you look up what Fox called the order when it was signed on Monday: "Child vaccine schedule reduced as Trump moves to dramatically shift medical power to parents." Power to parents — the empowerment frame, right there in the headline. The dek even described the plan as "spreading immunizations across five doctor visits," the way a brochure would. Now the Republican health chairman has run the same numbers and found what "spreading" means in practice: more visits, more missed work, more sick kids. Fox wrote the sales pitch and skipped the product recall. * We've been on this beat since day one, for the record. When the order was signed, we flagged that CNN's otherwise solid coverage never mentioned the small detail — carried by AP in its second paragraph — that separate measles, mumps and rubella shots aren't even available in the United States. Six days later the story has moved from "the shots don't exist" to "the president's own party says the plan makes kids sicker," and the coverage gaps have moved with it, from paragraph-nine omissions to entire-story omissions. * One pebble for CNN's shoe too, since we're here: its headline Sunday read "Trump's vaccine order is counterproductive and 'wrong on so many levels,' GOP lawmaker says." GOP lawmaker. The chairman of the Senate health committee, a doctor, the man who cast the deciding vote to confirm RFK Jr. — and the headline files him under the same label you'd give a freshman congressman from nowhere. The whole reason this is news is WHO said it, and the who didn't make the headline. * But anonymizing your source's job title is a misdemeanor. Booking Fauci to avoid covering your own side's rebellion — that's a choice about what readers are allowed to know happened today. Fox's audience will wake up Monday having never heard that the Republican Party's chief health policymaker thinks the vaccine order hurts the exact parents it claims to empower. They'll know all about a text message from 2021, though.
