President Bush is again defending a secret domestic eavesdropping program.
In a White House news conference today, the president told reporters he will continue using the program as long as the nation faces the threat of an enemy that wants to kill Americans.
He says a "two-minute phone conversation" between someone in the U-S linked to al-Qaida and operatives elsewhere could lead to the loss of thousands of lives.
The president says the program has been effective in disrupting the enemy, while "safeguarding our civil liberties." And he says it's done in a way that's consistent with U-S laws and the Constitution.
The program's existence was revealed in a New York Times article last week.
The president says it was "shameful" for someone to disclose this program in a time of war.
