President Biden took flak for a joke that seemingly implied the Irish are stupid.

After being introduced by House Speaker Nancy Pelosi, D-Calif., Biden began his remarks by turning to Rev. Thomas O'Connor, making the sign of the cross and joking, "Father, before I begin: Bless me, father, for I'm about to sin."

O'Connor jokingly responded by making the sign of the cross in response.

"Well, I just want you to know, I may be Irish, but I'm not stupid," Biden continued. "I married Dominic Giacoppa's daughter."

Dominic Giacoppa is the Sicilian name of Jill Biden's father, Donald C. Jacobs.

"You know, the good spirits and feelings as well that exist on St. Patrick's Day seems to be one of those few times — and I shouldn't say few — we should have more times like this for Democrats and Republicans to get together, and we actually not only agree on one thing, but we remind ourselves we actually like each other," Biden further said. "That's a useful thing."
