From Vatican Radio this morning:
"The pope has sent via the U.S. ambassador to the Holy See a message to Barack Obama. ... In the message, the pontiff sends best wishes to Obama and his family, calls this election a historic occasion and assures him of his prayers that God may assist him in his great responsibilities nationally and in the international community. Benedict XVI invokes God's blessing on the president-elect and on the American people in order that, with all persons of good will, they can build a world of peace, solidarity and justice."
