No, i really do believe that they were given to him by the Pope’s men at the meeting. It’s a token routinely given.
By the Pope’s men, not the Pope himself. And I guarantee you that if it did happen Obummer didn’t run up to the Pope and ask him to bless it. There is also no mention of a rosary being given by the Pope to the nassisist-in-chief in the official lists of exchanged gifts, which consisted of two medalians from the Pope and a copy of his apostolic exhortation, “The Joy of the Gospel”. This is much ado about nothing.
