Typically a break from partisan warfare, this year's Senate class photo turned smiles into snarls as Vice President Dick Cheney reportedly used a profanity toward one senior Democrat, sources said.

Sen. Patrick Leahy of Vermont, who was on the receiving end of Cheney's ire, confirmed that the Vice President used profanity during Tuesday's class photo.

A spokesman for Cheney confirmed there was a "frank exchange of views."

Using profanity on the Senate floor while the Senate is session is against the rules. But the Senate was technically not in session at the time and the normal rules did not apply, a Senate official said.

The story, which was recounted by several sources, goes like this:

Cheney, who as president of the Senate was present for the picture day, turned to Leahy and scolded the senator over his recent criticism of the vice president for Halliburton's alleged war profiteering....

Responding to Cheney's comment, Leahy reminded him of an earlier statement the vice president had made about him. Cheney then replied with profanity.

Leahy would not comment on the specifics of the story Thursday, but did confirm that Cheney used profanity.

"I think he was just having a bad day," said Leahy, "and I was kind of shocked to hear that kind of language on the floor."

A little over a year ago, when we launched the war against this second country, Iraq, President Bush repeatedly gave our people the clear impression that Iraq was an ally and partner to the terrorist group that attacked us, al Qaeda, and not only provided a geographic base for them but was also close to providing them weapons of mass destruction, including nuclear bombs.

But now the extensive independent investigation by the bipartisan commission formed to study the 9/11 attacks has just reported that there was no meaningful relationship between Iraq and al Qaeda of any kind. And, of course, over the course of this past year we had previously found out that there were no weapons of mass destruction in Iraq. So now, the President and the Vice President are arguing with this commission, and they are insisting that the commission is wrong and they are right, and that there actually was a working co-operation between Iraq and al Qaeda.

The problem for the President is that he doesn't have any credible evidence to support his claim, and yet, in spite of that, he persists in making that claim vigorously. So I would like to pause for a moment to address the curious question of why President Bush continues to make this claim that most people know is wrong. And I think it's particularly important because it is closely connected to the questions of constitutional power with which I began this speech, and will profoundly affect how that power is distributed among our three branches of government.

To begin with, our founders wouldn't be the least bit surprised at what the modern public opinion polls all tell us about why it's so important particularly for President Bush to keep the American people from discovering that what he told them about the linkage between Iraq and al Qaeda isn't true. Among these Americans who still believe there is a linkage, there remains very strong support for the President's decision to invade Iraq. But among those who accept the commission's detailed finding that there is no connection, support for the war in Iraq dries up pretty quickly.

And that's understandable, because if Iraq had nothing to do with the attack or the organization that attacked us, then that means the President took us to war when he didn't have to. Almost nine hundred of our soldiers have been killed, and almost five thousand have been wounded.

Thus, for all these reasons, President Bush and Vice President Cheney have decided to fight to the rhetorical death over whether or not there's a meaningful connection between Iraq and al Qaeda. They think that if they lose that argument and people see the truth, then they'll not only lose support for the controversial decision to go to war, but also lose some of the new power they've picked up from the Congress and the courts, and face harsh political consequences at the hands of the American people. As a result, President Bush is now intentionally misleading the American people by continuing to aggressively and brazenly assert a linkage between al Qaeda and Saddam Hussein....

They have such an overwhelming political interest in sustaining the belief in the minds of the American people that Hussein was in partnership with bin Laden that they dare not admit the truth lest they look like complete fools for launching our country into a reckless, discretionary war against a nation that posed no immediate threat to us whatsoever. But the damage they have done to our country is not limited to misallocation of military economic political resources. Whenever a chief executive spends prodigious amounts of energy convincing people of lies, he damages the fabric of democracy, and the belief in the fundamental integrity of our self-government.
