President Barack Obama celebrates St. Patrick's Day at the Dubliner Irish pub in Washington, DC with Ollie Hayes, right, owner of the pub in Moneygall, Ireland and Henry Healy, center, Obama's Irish cousin, on March 17, 2012.

The Associated Press reports — President Barack Obama tilted back a pint of Guinness Saturday, observing St. Patrick's Day at a boisterous Irish pub with his ancestral cousin from Moneygall, Ireland, at his side. 

Obama took his motorcade to the Dubliner Restaurant and Pub on a dazzling Saturday afternoon. Wearing a moss green jacket pierced with a button that read, "VIP GUEST — Tell 'em Danny sent you," the president waded into a crowd — some in leprechaun hats and others in dyed green hair — at the entrance of the tavern near Washington's landmark Union Station. 

Last year, Obama visited his ancestral home of Moneygall, a small hamlet in Ireland, and was a hit when he drank a Guinness at the local pub.

On Saturday, the owner of that pub, Ollie Hayes, and Henry Healy, an eighth cousin to Obama and the closest relative still living in Moneygall, joined him barside at the Dubliner as his guests.
