Obama hits golf course with Biden on another hot, humid weekend

President Barack Obama hit the golf course Saturday with Vice President Joe Biden.

The White House pool report noted that Obama left at about 1 p.m. for the course at Andrews Air Force base, and his golfing parters included White House Trip Director Marvin Nicholson and David Katz, the energy efficiency campaign manager at the Department of Energy.

Obama left the course shortly before 6 p.m.

Nicholson and Katz, along with Transportation Secretary Ray LaHood, joined Obama for four hours of golf last weekend. The Republican National Committee released an ad soon afterward taking aim at Obama's golfing during the ongoing BP oil spill crisis in the Gulf of Mexico.

The temperatures in the Washington, D.C., area Saturday were similar to last weekend, in the low 90s and humid.

Obama attended the Washington Nationals game Friday night wearing a cap for his hometown Chicago White Sox. Sources told the pool reporter that Obama sang "Take Me Out to the Ball Game" and left in the ninth inning, before the White Sox edged out the Nationals 2-1 in the 11th.
