"I presumed the president was being truthful until a series of events undercut that confidence."

"I would give relief from the first $10,000 of the payroll tax. I would allow small businesses to accelerate depreciation so they would have an incentive to buy now rather than defer. I would also give to the states $40 billion of relief."

"The president, clearly as a result of the war and the afterglow of the war, is in a time of great attention."

"Yes, more than 100 Democrats voted to authorize Bush to take the nation to war. Most of them did so in the belief that the president and his administration were truthful in their statements that Saddam Hussein was a gathering menace."

"I had earlier concluded that a war with Iraq would be a distraction from the successful and expeditious completion of our aims in Afghanistan. Now I had come to question whether the White House was telling the truth."

"The American people do not have the information upon which they can hold the administration and responsible agencies accountable. I call that a coverup."

"I voted no on the resolution to give the president authority to go to war against Iraq. I was able to apply caveat emptor. Most of my colleagues could not."

"Today 80 percent of all the oil that comes out of the Gulf is from 1,000 feet or more and today almost a third of it is more than 5,000 feet below the surface.

"It's fundamentally unfair to have so much of the tax relief go to so few. And it is a 10-year tax plan rather than one, as mine, focused on the next two years, which in my opinion is the critical time to jumpstart the economy."

"A significant number of pages and sentences that the administration wants to keep in a classified status have already been released publicly, some of it by public statements of the leadership of the CIA and the FBI."
