Not to smear Mother Theresa, but even though she was not there at the time, maybe she knew them from mutual friends, Charles Keating:
http://www.salon.com/sept97/news/news3.htmlIn 1992 she intervened with a court in Los Angeles, which was about to sentence Charles Keating, the biggest fraud and embezzler in American history. His S & L racket stole a total of $252 million, mainly from small and poor depositors. A strong Catholic and right-wing campaigner against pornography in his spare time, Keating gave Mother Teresa $1,250,000 in cash and the use of a private jet, in return for which she gave him many useful endorsements, including a character reference to the court. The court had asked Mother Teresa to return Keating's donations, which may well have been stolen, but she never replied to the request.
Maybe they had her on speed-dial in case McCain required intercession.
