Sen. Barrasso: 'Immigration is the backbone of the country'

Between 800,000 and 900,000 people are expected to crowd onto the National Mall today to watch President Obama recite the oath of office, a day after formally beginning his second term.

According to a recent CNN/ORC poll, 54% of Americans have above average expectations for the president's second term, whereas 41% describe their outlook as poor or below average.

One of the key issues Obama has said that he hopes to address in his second term is immigration, and Sen. John Barrasso talks with John King on Starting Point this morning about the GOP's willingness to tackle the important issue.
