President Obama will address the nation on a national security issue at 10:30 p.m. Eastern time Sunday, the White House said.
The announcement was abrupt, coming after the White House had declared a so-called lid, meaning no other news would be coming for the remainder of the day
And according to the breaking news on CBs, this is to announce of the death of Bin Laden and CBS sounded very sure of it.
