The University of Notre Dame is sticking with its invitation to President Obama to speak at its graduation commencement in May. But the President's invite has drawn criticism from Roman Catholics.

Some Catholics say the president's views on abortion and stem cell research counter the Catholic Church's teachings.

"Notre Dame's invitation to the most pro-abortion president in U.S. history is a betrayal of the University's mission and an affront to all who believe in the sanctity and dignity of human life," said Anthony J. Lauinger, National Right to Life Vice-President (and father of seven Notre Dame alumni and one current student.) 

"We call upon Father Jenkins to rescind the invitation and stand up for the millions of unborn children who face death under Obama Administration policies," he continued.

More than 33,000 people have signed a petition to withdraw the president's invitation.

However, a Notre Dame spokesman says that's not very likely to happen.
