At Obama's press conference, which lasted nearly a full hour, Obama called on a wide array of reporters, representing media organizations from the Detroit News to the Associated Press. He also called on all three major networks ABC, NBC and CBS.
But not Fox News. Fox (its sister network) decided not to carry Obama's press conference live, instead deciding to run the drama "Lie to Me." The networks generally carry presidential press conference live, but executives have grumbled because the events shave advertising dollars off the evening's schedule.
