In light of the Boston Marathon explosions, TV networks dedicate their programs to the tragedy. NBC even plans to preempt its primetime series "Revolution" on Monday night, April 15 and replace it with a Brian Williams-anchored news special. Matt Lauer, Lester Holt, Ron Allen, Pete Williams, Katy Tur and more will contribute to the reports.
Earlier the night, at 6:30 P.M., Brian Williams hosted a special one-hour edition of "NBC Nightly News" featuring live reports from Boston. The next day, Lauer will anchor "Today" live from Boston, while Savannah Guthrie will still film the show in New York.
No primetime changes are planned at ABC, CBS and FOX, but the Tuesday edition of ABC's "Good Morning America" will have a special coverage on the tragedy with George Stephanopoulos and Josh Elliott reporting from Boston. CBS has expanded "CBS Evening News with Scott Pelley" to an hour on Monday night, while Fox News Channel preempted "The Five" for live coverage from Boston with anchor Shepard Smith.
CNN, meanwhile, has sent Chris Cuomo and Anderson Cooper to Boston to report from the scene, with coverage to air every an hour starting at 7 P.M. ET to 12 A.M. ET. MSNBC's "The Rachel Maddow Show" will air live from Boston on Monday night, while Joe Scarborough and Mika Brzezinski will host "Morning Joe" on Tuesday morning also from Boston.
On Monday morning, two bombs exploded near the finish line of the annual Boston Marathon. Three people died in the incident, and at least 133 people were injured. Boston Police Commissioner Ed Davis said, "There's no suspect at Brigham and Young Hospital. There are people we are talking to, but no suspect."
In a statement from the White House press room, President Obama said, "The American people will say a prayer for Boston tonight. We don't yet have all the answers, but we do know multiple people have been wounded, some gravely, in explosions at the Boston Marathon."
"We still do not know who did this, or why. People shouldn't jump to conclusions before we have all the facts. But make no mistake, we will get to the bottom of this. We will find out who did this and we will find out why they did this. Any responsible individuals, any responsible groups, will feel the full weight of justice ... we will hold them accountable."
