ABC will have a special edition of "20/20" anchored by Chris Cuomo from Aurora and Diane Sawyer from New York, tonight at 10. There's a special edition of "Nightline" on ABC at 11:35. On CNN, Anderson Cooper will broadcast "AC360" from Aurora at 8 p.m. and 10 p.m.  On Fox, "On the Record with Greta Van Susteren" will cover the shooting at 10, with Van Susteren reporting from Aurora. Chris Jansing will have special reports from Colorado at 4 and 10 on MSNBC.
