I did not know this...

Which is to the McCains' credit, because lesser people ("Brangelina" and Madonna, I'm looking at you) would have totally used this for publicity whoring:

Gateway Pundit: Obama Talks About Lifting a Child In Bangladesh From Poverty... John McCain Already Did

From the linked Wall Street Journal article (written by "teh eeeevil" Karl Rove):

For example, in 1991 Cindy McCain was visiting Mother Teresa's orphanage in Bangladesh when a dying infant was thrust into her hands. The orphanage could not provide the medical care needed to save her life, so Mrs. McCain brought the child home to America with her. She was met at the airport by her husband, who asked what all this was about.

Mrs. McCain replied that the child desperately needed surgery and years of rehabilitation. "I hope she can stay with us," she told her husband. Mr. McCain agreed. Today that child is their teenage daughter Bridget.

I was aware of this story. What I did not know, and what I learned from Doris, is that there was a second infant Mrs. McCain brought back. She ended up being adopted by a young McCain aide and his wife.

"We were called at midnight by Cindy," Wes Gullett remembers, and "five days later we met our new daughter Nicki at the L.A. airport wearing the only clothing Cindy could find on the trip back, a 7-Up T-shirt she bought in the Bangkok airport." Today, Nicki is a high school sophomore. Mr. Gullett told me, "I never saw a hospital bill" for her care.

A few, but not many, of the stories told to me by the Days have been written about, such as in Robert Timberg's 1996 book "A Nightingale's Song." But Mr. McCain rarely refers to them on the campaign trail. There is something admirable in his reticence, but he needs to overcome it.

Emphasis mine.
