(CNN) -- President Bush had a "relaxed" and "friendly" meeting with President-elect Barack Obama after he and first lady Laura Bush welcomed their successors to their future home Monday, a White House spokesman said.

President Bush and Laura Bush welcome Barack and Michelle Obama to the White House on Monday.

"The president and the president-elect had a long meeting, described by the president as good, constructive, relaxed and friendly," White House press secretary Dana Perino said in a statement. "The president enjoyed his visit with the president-elect, and he again pledged a smooth transition to the next administration."

Perino said the two discussed national and international issues but did not provide specifics of the conversation. Bush also gave Obama a tour of the White House's living quarters, including the Lincoln bedroom.

Bush and Obama held a private meeting in the Oval Office, while the first lady gave 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 were not expected to speak on camera after their meeting.

The two met in the Oval Office for just over an hour. When President George H.W. Bush hosted President-elect Bill Clinton after the 1992 election, the two talked for nearly two hours.

Monday's meeting was a historic formality, but it was also a time for serious talks. It marked the first time Obama has visited the Oval Office.  Watch Bush welcome Obama to the White House Â»

Bush and Obama "had a broad discussion about the importance of working together throughout the transition of government in light of the nation's many critical economic and security challenges," said Stephanie Cutter, spokeswoman for Obama's transition team.

"President-elect Obama thanked President Bush for his commitment to a smooth transition, and for his and first lady Laura Bush's gracious hospitality in welcoming the Obamas to the White House," Cutter said.

A day earlier, a leader of Obama's transition team said the president and president-elect were expected to discuss "a broad range of issues," focusing on the economy.

"It's clear that we need to stabilize the economy, to deal with the financial meltdown that's now spreading across the rest of the economy. The auto industry is really, really back on its heels," transition team leader John Podesta told CNN's "Late Edition" on Sunday.

Podesta said Obama will push Congress to enact "at least part" of an economic package before he takes office in January, but said the problems Americans face need short- and long-term approaches.

The president and president-elect also were expected to talk about national security and the war in Iraq. Go inside the Oval Office
