The most memorable moment of Barack Obama's address at the memorial service in Tuscon Wednesday was when he gave the crowd the good news that Congresswomen Gabrielle Giffords, who was critically wounded in the shooting on Saturday, had opened her eyes.

Congresswoman Debbie Wasserman Schultz was actually in the hospital room when this happened, and she recounted the experience on 'Anderson Cooper 360' (Weekdays, 9 PM ET on CNN)

"We were talking to her and I said, 'come on, you get to get better as quickly as possible, because we expect you up at New Hamphsire this summer. ' And, just as I said that, that's when she suddenly started struggling to open her eyes, first just a little bit, the doctors couldn't believe it."

"She went from opening her eyes really just a slit, to opening them almost fully," Wasserman continued. "Anderson, it was the most incredible -- other than the birth of my kids -- it was the most incredible experience I've ever had."
