On its official Twitter account on Sunday, the party shared a doctored version of O’Rourke’s mugshot showing him wearing a cartoon leprechaun hat and holding a placard with the message: “Please Drink Responsibly.”

“On this St. Paddy's Day, a special message from noted Irishman Robert Francis O'Rourke,” the tweet read.

O’Rourke, who announced last week that he is jumping into the 2020 presidential race, brushed off the criticism as “pettiness,” and said that voters are not interested in “personal attacks.”
