CNN-YouTube Debate controversy
On November 28, 2007, Kerr submitted a YouTube video that was used as a question in the Republican Presidential Debate in St. Petersburg, Florida on CNN. Kerr was also present in the audience and was asked to speak in which he said: After the candidates responded Anderson Cooper asked him if he got an answer to his question to which he replied, "With all due respect, I did not get an answer from the candidates." Kerr's question generated criticism of CNN for not disclosing Kerr's Clinton ties. CNN had paid Kerr's traveling expenses to the debate but stated that it was unaware of the connection with the Clinton campaign at the time. When asked if anyone affiliated with the Clinton campaign "put you up to the idea of asking this question," Mr. Kerr stated that "his was a private initiative of my own." CNN pulled Kerr's question and response in subsequent replays.
