WASHINGTON — President Obama startled members of the White House press corps yesterday when he walked through their working area of the West Wing.

"Good to see you guys. I just wanted to make sure that I had a chance to say hello," Obama said on his second full day on the job.

Without any notice, the president walked through the press briefing room, causing a bit of a wild scene. Reporters started running toward him, wary of missing a single word. When one reporter who hadn't spotted Obama yet asked what everyone was rushing toward, another one responded: "The big guy."

When a reporter tried to quiz him about a lobbyist chosen for a top Defense Department job, Obama begged off. "I came down here to visit. I didn't come down here — this is what happens. I can't end up visiting you guys and shaking hands if I am going to (get) grilled every time I come down here."

Obama was willing to field some lighter questions. Yes, he's discovered the gym in the White House residence. No, he hasn't played basketball yet on the outdoor White House court because it's been too cold.

OBAMA GIRLS GO BACK TO SCHOOL

WASHINGTON — It was back to business yesterday for first daughters Sasha, 7, and Malia, 10, as they returned to classes at the private Sidwell Friends School.

The girls were allowed to play hooky Wednesday after a late-night scavenger hunt at the White House that ended when they opened a door and found their favorite band, the Jonas Brothers.

But two days of frivolity was, apparently, enough. Michelle Obama had no public schedule for the rest of the week as she helped the girls make themselves at home, said Michelle Obama's spokeswoman, Katie McCormick Lelyveld.

Both girls were excited to get their rooms set up, McCormick Lelyveld said.

"I know the family's moved now three times in only a few weeks. But if you know them and you know their family, they've had a routine for a long time," Gibbs said. "This is a monumental testament to Michelle."
