Trying to get some last minute holiday donations, the global health charity PSI has been sending out almost daily emails penned by their celebrity ambassadors, many of whom have also testified before Congress or visited Washington on the group's behalf.

So far Yeas & Nays received notes from Mandy Moore, Debra Messing, Ashley Judd and tennis player Anna Kournikova. In Kournikova's email, she contrasted her privileged upbringing to those of children in the developing world. "I say that I'm fortunate because if I were born a girl in the developing world, chances are, I would have never stepped onto the tennis court," Kournikova wrote in a fundraising plea sent out Friday. The group draws attention to HIV/AIDS and also ailments that affect children under the age of 5, such as malaria, diarrhea, pneumonia and malnutrition.
