A U.S. lobbying group is protesting the decision to have Argentina's president ring the opening bell at the Nasdaq stock exchange on Monday.

American Task Force Argentina says the South American nation's government "has defied hundreds of judgments" in U.S. courts and still owes investors billions following its debt default.

Executive Director Robert Raben said Friday that President Cristina Fernandez "doesn't deserve the honor" of ringing the Nasdaq bell. The group said it has sent nearly 30,000 protest letters to the exchange and the Departments of State and Treasury.

Argentina defaulted on $95 billion in 2001. Most was restructured in 2005. But U.S. investors say they are still owed more than $3 billion.
