Republican National Committee Chairman Reince Priebus entreated Republicans on Thursday to not appear on MSNBC presentations as a result of a tweet from the network that mentioned “the rightwing” may disapprove of a Cheerios tv advert that includes a biracial household. Priebus despatched a letter to MSNBC President Phil Griffin disturbing an apology. The cable information community’s tweet on Wednesday stated, “Perhaps the rightwing will hate it, but everybody else will go awww: the adorable new #Cheerios ad w/ biracial household” to promote an MSNBC story on the breakfast cereal business, so as to be broadcast right through Sunday’s Super Bowl. The ad stars Grace Colbert, 6, as the daughter of a fictional biracial couple.
