It was not until he got a quiet word of correction in his ear from Senator Joseph I. Lieberman of Connecticut, who was traveling with Mr. McCain as part of a Congressional delegation on a nearly weeklong trip, that Mr. McCain corrected himself.
“I’m sorry,” Mr. McCain said, “the Iranians are training extremists, not Al Qaeda."
Democratic leaders agreed to a request by Republicans for the extraordinary session, on legislation opposed by President George W. Bush.
So what went wrong with Mr Romney's well-financed campaign?
Mr Romney had attempted to run as the legitimate heir of Ronald Reagan, one of the most popular Republican presidents in recent times, a "conservative's conservative."
He had the looks, the personality and the money to be a credible Republican presidential candidate.
And as a Republican governor in a Democratic state, he appeared to have the potential to reach out beyond the Republican base.
Credibility problem
But Mr Romney had a big credibility problem among Republican primary voters, who were not convinced by his conversion from a liberal Massachusetts governor to a conservative candidate for national office.
His "flip-flop" on a universal health care mandate, which he had introduced in Massachusetts but repudiated nationally, was one commonly cited example.
Conservatives were also suspicious about his changed views on social issues like abortion.
This served to alienate him from the Christian right, a key group within the Republican party, which was already suspicious of his Mormon religion.
In the primary elections on Tuesday, most Christian evangelicals backed Mike Huckabee, taking enough votes away from Mr Romney to give victory to John McCain in key states like California and New York.
Although he won a number of smaller states, especially those who chose their delegates by caucus, his weak showing in his home state of Massachusetts, which he only narrowly carried, was an early indication of his fading campaign.
Radio talk show host Rush Limbaugh drew media attention to himself last week when he suggested he might not support McCain if he became the Republican nominee. Now Ann Coulter has upped the ante, telling Fox News host Sean Hannity that if John McCain is the Republican nominee, she's supporting Hillary Clinton.
"If he's our candidate, then Hillary's going to be our girl," Coulter asserted. "Because she's more conservative than he is. I think she would be stronger on the war on terrorism. ... I absolutely believe that. ... I will campaign for her if it's McCain."
