Starting Point

Starting Point Primary Sources for Thursday, March 1st.

Here are three primary sources that were referenced in today's "Starting Point with Soledad O'Brien" –

* Our top story was the devastation caused by tornadoes in the Midwest. Tornado strength can be measured on the "F-scale," which is named after T. Theodore Fujita. For more information on the F-scale, visit this website from the National Oceanic and Atmospheric Administration.

* Christine Romans interviewed The Edge, U2's longtime guitar player. The Edge is taking part in a new MTV documentary that addresses the issue of homeless young people. "The Break" is hosted by Anne Mahlum, who founded the non-profit Back on My Feet program, which also assists the homeless. For more information about The Break, including the trailer, visit MTV's webpage for the show.

* Nada Bakri, the widow of New York Times reporter Anthony Shadid who died last month while on assignment in Syria, talked with Soledad live this morning about her husband's legacy.
