U.S. President-elect Barack Obama and the outgoing President George W. Bush wrapped up their talks at the White House Monday, without making any comments to the public.

Without going into the details, the White House spokeswoman Dana Perino said the meeting was "good, constructive, relaxed and friendly."

Bush and Obama held a private meeting in the Oval Office, while the first lady Laura Bush gave the incoming first lady Michelle Obama a tour of the residence.

The president and president-elect walked together along the colonnade by the Rose Garden before entering the Oval Office together.

They briefly waved to reporters along the way.

Obama and Bush spoke on camera following their meeting, which lasted for nearly two hours.

An aide to Obama said they were "going to let the pictures speak for themselves."
