: "Bush is under the worst pressure of his two terms in office and his popularity is near an all-time low. The handling of the Katrina crisis and troop losses in Iraq have fueled public discontent and pushed Bush back to drink.

A Washington source said: "The sad fact is that he has been sneaking drinks for weeks now. Laura may have only just caught him — but the word is his drinking has been going on for a while in the capital. He's been in a pressure cooker for months.

"The war in Iraq, the loss of American lives, has deeply affected him. He takes every soldier's life personally. It has left him emotionally drained.

The result is he's taking drinks here and there, likely in private, to cope. "And now with the worst domestic crisis in his administration over Katrina, you pray his drinking doesn't go out of control."

Another source said: "I'm only surprised to hear that he hadn't taken a shot sooner. Before Katrina, he was at his wit's end. I've known him for years. He's been a good ol' Texas boy forever. George had a drinking problem for years that most professionals would say needed therapy. He doesn't believe in it [therapy], he never got it. He drank his way through his youth, through college and well into his thirties. Everyone's drinking around him.""
