The cables shows today covered a bit about how a Trump surrogate had to apologize for posting Hillary in blackface.
One poll that I saw said that 93% of those polled said that the Trump campaign should apologize too.
I do not believe that a campaign is responsible for every surrogate out there. Unless the campaign told him to do so, they don’t need to apologize.
What I’d rather see would be for them to take the opportunity to issue a short statement on why it might be wrong and help educate on the issue.
