Michelle Obama last week criticized the makers of Beanie Babies for introducing a pair of dolls named Sasha and Malia. Ty Inc. says it used the names for the new dolls in its TyGirlz line because they are “beautiful names,” not because they happen to be the names of the First Daughters. “There’s nothing on the dolls that refers to the Obama girls,” said a spokeswoman. In a statement, Michelle Obama said it was “inappropriate to use young, private citizens for marketing purposes.”
