WASHINGTON - In honor of St. Patrick's Day today, the White House has dyed the fountain on the South Lawn green to celebrate.

President Obama spent most of St. Patrick's Day at the White House, but went out Saturday afternoon to play basketball with his 11-year-old daughter Sasha at the Department of Interior.

While his weekend was quiet, the president will continue his St. Patrick's Day celebration on Tuesday, first attending the traditional St. Patrick's Day lunch at the Capitol. In the evening, the president and first lady will host Ireland's Prime Minister Enda Kenny for a St. Patrick's Day reception at the White House. The president and Kenny will participate in the annual Shamrock ceremony, a tradition that dates back to the presidency of Harry Truman.

Last year, Obama popped into the Dubliner, a pub on Capitol Hill, for a Guinness and a toast with the crowd.
