Season's greetings from President Obama.
The president - or at least the manager of his Twitter account - sent out a simple tweet Sunday morning: "Happy St. Patrick's Day!"
We assume the twitter was wearing green.
An attached pictured shows Obama hoisting a hearty Guinness during a St. Patrick's Day visit last year to an Irish pub in Washington, D.C.
We wouldn't be surprised to see a similar presidential visit later Sunday.
