NBC raises issues with Romney campaign use of Brokaw news clip

A Romney Florida campaign ad shows then-NBC anchor Tom Brokaw saying that some of Gingrich's House colleagues had raised questions about the then-speaker's "future effectiveness."

A letter from NBC to the Romney campaign: "Aside from the obvious copyright issues, this use of the voice of Mr. Brokaw and the NBC News name exploits him and the journalistic credibility of NBC News,"

Brokaw noted he was "extremely uncomfortable with the extended use of my personal image in this political ad. I do not want my role as a journalist compromised for political gain by any campaign."
