President Bush will defend his controversial domestic spying program Monday during a speech at a university in the midwestern U.S. state of Kansas.
The president's speech is part of an intense effort by the administration to convince the nation that the program is a necessary tool to fight terrorism.
The former head of the National Security Agency, General Michael Hayden, will also deliver a speech today defending the program. And Attorney General Alberto Gonzales will address the issue Tuesday, one day before President Bush visits NSA headquarters near Washington.
Mr. Bush has come under fire for authorizing the NSA to conduct electronic surveillance on U.S. citizens without first getting permission from a special court.
Opposition Democrats, along with members of the president's own Republican Party, have questioned the legality of the program.
