Of course, he apologized:
I have seen the video posted on several blogs. I deeply and profoundly regret my reaction, and I apologize to all involved. Throughout my many years of service to the people of North Carolina, I have always tried to treat people from all viewpoints with respect. No matter how intrusive and partisan our politics can become, this does not justify a poor response. I have and I will always work to promote a civil public discourse.
The seven-term Democrat from North Carolina’s Second CD is looking pretty safe. He’s raised more than $735,000 compared to his closest GOP opponent, Renee Elmers, who has only raised $73,000. Still, I wonder how long it takes the NRCC to make this into a campaign video?
