(CNN) - Asked about the criticism that he is inexperienced, entering the presidential race as a first-term senator, Sen. Barack Obama, D-Illinois, responded by saying that "people have an urgent desire for change in Washington."
Obama defended his experience and said he brings the perspective of a community organizer and state legislator, in addition to his role in Congress.
"We're not going to fix health care. We're not going to fix energy. We're not going to do anything about our education system unless we change how business is done in Washington," Obama said.
