A Newsweek article found via TPM:
Last Tuesday afternoon, a day before President George W. Bush went on TV to explain his decision to send more troops to Iraq, Senate Minority Leader Mitch McConnell called his Republican colleagues together for a private talk. Several GOP senators had already come out against the plan. McConnell, Bush's closest Senate supporter on Iraq, hoped to keep others from defecting. He urged his colleagues to stand together at least until Bush had the chance to speak to the country.
After the meeting, the senators went outside the room to display their unity to waiting reporters. McConnell said he thought more troops were just the thing to "give us a chance to succeed." He then stepped aside so the other senators could second his sentiments. No one came forward. McConnell's eye fell on Trent Lott. "Trent?" McConnell said, motioning him toward the microphone. "I don't think I have anything to add," said Lott.
