(CNN) - The McCain campaign suspended a staff member Thursday afternoon for distributing a YouTube video that questions Barack Obama's patriotism and includes footage from the Rev. Jeremiah Wright's controversial sermons.
“We have been very clear on the type of campaign we intend to run and this staffer acted in violation of our policy. He has been reprimanded by campaign leadership and suspended from the campaign,” McCain campaign spokeswoman Jill Hazelbaker said.
The suspended staffer, Soren Dayton, works in the campaign's political department and distributed the YouTube video via the internet application Twitter earlier Thursday.
A campaign aide insists Soren Dayton was a low level staffer and who had “no role in the communications shop.”
McCain insists repeatedly that he will not engage in personal attacks on Democrats, and CNN was told last week that campaign aides are working on an op-ed to be published in the senator's name warning his surrogates and supporters not to do so.
