The GOP aide wasn't "for Brett Kavanaugh". The GOP aide wasn't even an "aide for the nomination" since Trump nominated Kavanaugh. No, the aide was the spokesman for Grassley's committee. Kavanaugh had no say whatsoever in who works for Grassley and who doesn't.
Total cheap shot. Total bs. Totally corrupt manipulation of language.
No wonder CNBC closed comments on its articles long ago. They're all like this.
