Nancy Pelosi recalled calling her daughter on Christmas to find out what the filmmaker's kids got for Christmas.
"She said, 'Mom I'm not going to tell you where I am right now,' and I said, 'Well, I think you are because you brought it up,'" the House Democratic minority leader recalled.
She was in prison with McGreevey: the younger Pelosi recalls her mother didn't take the news well, chastising her for not being home with her children, now 5 and 6.
"I thought, 'There's something more important than me and my kids,' and that's something I learned from Jim McGreevey," Pelosi said.
Pelosi said after that conversation with her mother, "I wasn't sure how supportive my mom was of the project — until today."
The debut of the film marked a career pinnacle for Pelosi, a former NBC News journalist; having Redford appear at the film's premiere was an added bonus.
"Robert Redford was famous and could have retired after 'Butch Cassidy and the Sundance Kid,'" she said, referencing one of his most famous films.
"But he kept working and his best work was in front of him, and if you ask me, Robert Redford's best work is Sundance because he makes everybody else's dream come true," she continued.
"He's using his fame for good, just like Jim McGreevey is using his shame for good."
