At Pelosi's side were Georgia congressman and civil rights-era leader John Lewis and her close friend Rep. David Obey (D-Wisc.).
Speaking to HuffPost's Arthur Delaney, Rep. Dingell expressed confidence that reform would pass when asked if he thought Democrats had the votes.
"I wouldn't be walking this way if I didn't," said the Michigan Democrat, who ambled into the meeting on crutches instead of in a wheelchair. The caucus could be heard applauding him when he entered the room.
Rep. Alan Grayson (D-Fla.) told HuffPost that Rep. Bart Stupak (D-Mich.) and his anti-abortion bloc of Democrats were not discussed during a last-minute morning meeting of Democrats. He echoed Speaker Pelosi in saying he expected the bill would pass. Asked whether Stupak would be a 'yes' vote, Rep. Sandy Levin said, "I think so."
