Ken Cuccinelli walked into a bar. And Martin O’Malley lit into him.

The two political polar opposites crossed paths Wednesday night at the Dubliner, a Capitol Hill Irish pub popular on Thanksgiving Eve with Gonzaga High School graduates. Both men attended the school, graduating five years apart in the 1980s.

Siobhan Arnold, who was visiting from Philadelphia, had just met O’Malley at the bar when Cuccinelli walked in. Soon the two men were face-to-face, she said, with O’Malley excoriating Cuccinelli over the Trump administration’s immigration policies.

O’Malley said “something about his [Cuccinelli’s] grandparents,” Arnold said in an interview. Cuccinelli said little if anything in reply, she added, quickly leaving the pub.

“O’Malley was shouting,” Arnold said. “I don’t think Cuccinelli was responding. I think he’s like, ‘Time to go. Just got here and I’m leaving.’ He pretty much retreated.”
