Sunday’s talk-show lineup: Nuclear crisis and the no-fly zone

Update: After U.S. and international forces began military strikes on Libya, Adm. Mike Mullen, the chairman of the Joint Chiefs of Staff, has been added to the top of the guest list on ABC, CBS, CNN, Fox and NBC.

Steven Chu will be the lead guest on all five major Sunday talk shows this week. The secretary of Energy and Nobel Prize winning scientist will talk about the nuclear crisis in Japan and will likely be asked about the future of nuclear power in the United States.

A former energy secretary will be on ABC’s “This Week,” as well. Bill Richardson, who served in that position in the Clinton administration, will join former Secretary of Homeland Security Michael Chertoff.
