Apparently not...
"The at-issue email and social media posting was not sanctioned by the Cruz for President campaign," said Alice Stewart, a spokeswoman for Mr. Cruz. "The campaign became aware of the email this morning by press accounts, and upon investigation learned that some volunteers in Hawaii were involved in the posting."
So is the Trump campaign and Trump himself personally responsible for everything posted on this forum by one of his supporters? Or is it possible that some supporters will post or send some things that the campaign might not like?
