The Republican Party honored St. Patrick’s Day by sending a tweet mocking presidential hopeful Beto O’Rourke’s Irish heritage.

The tweet from the GOP’s official Twitter account featured an image of O’Rourke’s mug shot from a 1998 drunk-driving arrest. The former Democratic representative was charged with DWI at age 26 when he crashed into a truck on an interstate.

The mug shot in the tweet was photoshopped to include a cartoon leprechaun hat over his head and a placard across his chest that read, “PLEASE DRINK RESPONSIBLY.” Along with the image, the GOP tweeted the message, “On this St. Paddy’s Day, a special message from noted Irishman Robert Francis O’Rourke.”

When O’Rourke challenged Texas Sen. Ted Cruz (R) in the 2018 midterm election, Republicans often criticized O’Rourke for going by “Beto,” a childhood nickname that stuck, rather than Robert.
