Pitt says fatherhood has made him an activist

Brad Pitt says fatherhood is "absolutely sublime" and that being a father has made him more of an activist on child poverty.

"Whether you have them or adopt them, they're all blood," Pitt said of his brood.

"I look at Zahara and imagine what her life could have been. You want to grab as many of these kids in your arms as you can. They need our help and we should be doing more."
