Tuesday night (10/20) at 8:00 p.m. Central, SDPB-TV premieres "Immigration Battle," a special two-hour feature film presented by FRONTLINE and INDEPENDENT LENS. Acclaimed independent filmmakers Shari Robertson and Michael Camerini take viewers behind closed doors in the nation's capital to explore the political realities surrounding one of the country's most divisive issues - immigration. "Immigration Battle" reveals the untold story of the push for bipartisan immigration reform after President Obama's reelection. The film is a fly-on-the-wall look at the high stakes effort to broker a deal in Congress - an effort led by Rep. Luis Gutierrez (D-IL). SDPB's Steve Zwemke visited with filmmaker Shari Robertson to learn more about the behind the scenes negotiations.
