President Obama's Second Address to the UN General Assembly

President Obama made his second major speech to the UN General Assembly today. We hear different opinions about what he said about US engagement with the rest of the world and what he left out. Also, Republicans unveil their "Pledge to America," and a new study on the need for mammograms to detect breast cancer.
