Then why did his campaign admit that he did?
The word "fabricated" was used in the headline. If you can find where it was used by his campaign please provide a quote.
They didn’t admit it. Note: Just because a reporter writes something, or an editor fashions a headline, does not make it true. They said that the campaign admitted it, but the campaign says that is not true. Who do you believe - Politico’s hack journalist, or Dr. Ben Carson?
