WASHINGTON // The US President-elect Barack Obama visited the White House yesterday for his first post-election meeting with George W Bush, a strikingly symbolic moment in the transition of power. The president and the first lady, Laura Bush, greeted Mr Obama and his wife, Michelle, with smiles and handshakes, even as Mr Obama's advisers reviewed some of Mr Bush's executive orders with an eye to reversing them after he is sworn in on Jan 20. The two men met privately in the Oval Office for more than an hour for talks thought to have encompassed the global financial crisis, the wars in Iraq and Afghanistan and other daunting challenges the Republican president will bequeath to his Democratic successor. It was their first face-to-face encounter following Mr Obama's resounding victory over Republican John McCain in last week's election, which will make him the United States' first black president. Mr Obama, 47, had repeatedly attacked Mr Bush's "failed policies" on the campaign trail, and the Illinois senator swept to power on a theme of change - specifically, change from the unpopular president's approach to economics and foreign affairs. Mr Obama's aides say after taking office he will likely move quickly to roll back Mr Bush's executive orders that limit stem cell research and expand oil and gas drilling in some areas. There was no outward sign of tension, however, when the Obamas stepped from their limousine at the south portico of the White House. Earlier, they had been cheered by crowds of onlookers as their motorcade sped through the capital. "Good morning," Laura Bush chirped, though it was well past noon. Mr Obama put his hand on Mr Bush's back cordially as the two couples entered the mansion. The leaders then strolled down the colonnade side by side, chatting. Mr Obama was the more animated of the two, gesturing with both hands. He had never set foot in the Oval Office before and was ushered in ahead of Mr Bush. While their husbands met, the first lady gave Michelle Obama a tour of the White House living quarters, which will soon be her family's new home and where daughters Malia, 10, and Sasha, 7, will be running the halls. At the end of a two-hour visit, Mr Bush and Mr Obama had nothing to say to reporters and both camps were mostly tight-lipped. A White House spokeswoman, Dana Perino, would only say that domestic and international issues were discussed and that Mr Bush "again pledged a smooth transition". Stephanie Cutter, Mr Obama's spokeswoman, said the leaders agreed on the need to cooperate in the changeover "in light of the nation's many critical economic and security challenges". Later, as Mr Obama's plane sat on the airport tarmac in Washington before taking off for Chicago, journalists onboard overheard snippets of a cellphone conversation the president-elect had with an unknown party. "I am not going to be spending too much time in Washington over the next several weeks," Mr Obama said. Newly elected presidents traditionally visit the White House between election and inauguration but usually wait longer than Mr Obama did. He came calling at Mr Bush's invitation after only six days, underscoring a sense of urgency in the transition. It will be the first wartime transfer of power in four decades and comes amid economic upheaval at home and abroad. Financial markets, struggling in a global credit crunch, are awaiting news of Mr Obama's appointments for key jobs such as Treasury secretary, but a spokeswoman for Mr Obama said he would not make any Cabinet announcements this week. Mr Obama said in his first post-election news conference on Friday he would not be rushed into making hasty decisions. Underscoring Mr Obama's assertion he will not act as a shadow president during the transition, an aide confirmed what the White House had been saying - he will not attend a global financial summit in Washington on Nov 14-15. Mr Bush, whose low approval ratings helped propel Mr Obama to victory, has said he will do all he can to help in the changeover. Mr Obama had impugned Mr Bush's leadership at every turn during the bitter election campaign, depicting Mr McCain as the president's clone. Many analysts saw Mr Obama's victory in part as a rebuke by voters of Mr Bush's two terms in office. But the two have made clear they are now setting politics aside, as symbolised by the collegial tone of the visit. Though visits by incoming presidents to the White House before taking office are a ritual dating back decades, there was little denying Mr Obama's tour carried special significance. *Reuters
