The Republican National Committee drew outrage for stoking an ethnic stereotype Sunday, tweeting a St. Patrick’s Day message of “please drink responsibly” with a doctored photo of Democratic presidential candidate — and “noted Irishman” — Beto O’Rourke’s 1998 mugshot for a DUI arrest.

Speaking in Wisconsin on Sunday, O’Rourke did not address the tweet directly, but spoke in more general terms about the state of political discourse: “We cannot meet this challenge with more partisanship, more pettiness, more meanness, more personal and partisan attacks.”
