Bush Summons Cabinet to White House
Thursday March 20, 2003 7:10 PM
WASHINGTON (AP) - President Bush, leading the nation into war a second time, summoned his Cabinet to the White House on Thursday as officials sought to determine whether attacks aimed at killing Saddam Hussein and other Iraqi leaders had succeeded.
In a White House cloaked by extraordinary security, aides dismissed criticism from abroad while U.S. officials said explosions in Baghdad and U.S. artillery fire on Iraqi troops were a prelude to a massive assault on Iraq, due any time.
Behind the scenes, White House officials said early reports from the battlefield were encouraging, raising hopes that senior Iraqi leaders may have been captured or killed, perhaps even Saddam.
While cautioning against speculation, government officials said intelligence information suggested that Iraq's leadership was in disarray after the attacks. The administration raised doubts about whether television footage of Saddam was authentic.
