"My number one priority in the coming two months is to try to facilitate a transition that ensures our president-elect is successful", Obama said, noting if Trump succeeds the country will succeed.
Trump, sitting in the office he will soon redecorate, described the discussion as an opportunity for the two men to get to know each other and professed to have "great respect" for the sitting president.
White House officials say President Barack Obama is prepared to spend his final major foreign trip talking about Donald Trump.
"This is unlike how things have worked for previous presidents-elect, and is not at all how the Obama White House handles press access", said Edward-Isaac Dovere, the Politico reporter who handled the pool report for Thursday's visit. But the lack of genuine warmth in their body language was evident. "Really good meeting, great chemistry", Trump said on Twitter late on Thursday. Both Obama and first lady Michelle Obama attacked Trump as temperamentally unfit for the White House and dangerously unprepared to have access to USA nuclear codes.Both Obama and Trump sought to change the bitter election tone right after Trump's unexpected election victory.On Wednesday, Obama said that despite his major differences with Trump, he would follow the lead of former Republican President George W. Bush in 2008 and ensure a smooth handover to Trump.
Obama said he and Trump had an "excellent" and "wide-ranging" conversation about domestic policy and world affairs, and he urged Americans to rally behind their soon-to-be leader at a time when angry protesters have taken to the streets in several cities to reject Trump's election. Nearly two-thirds said they didn't think Clinton was honest and trustworthy while nearly 6 in 10 felt that way about Trump.
On the East Coast, protests took place in Washington, Baltimore, Philadelphia and NY, while on the West Coast demonstrators rallied in Los Angeles, San Francisco, Oakland and Portland. At least 26 people were arrested in Portland, while at least 35 were arrested in Los Angeles for failing to disperse during their protest.
If he handed the baton to Trump in the Oval Office on Tuesday, then his meeting with Merkel in Berlin may be the passing of the liberal democratic torch.
Trump headed from the White House to Capitol Hill for a lunch meeting with House Speaker Paul Ryan.
"They informed us last night that they would not provide flight access from NY to D.C. They did not respond at all this morning to questions about access, having referred it all to the White House and White House Correspondents' Association", he said. Ryan, who holds the most powerful post in Congress, was a sometime critic of Trump and never campaigned with the nominee.
The apparently harmonious meeting between Trump and Obama was created to heal divisions and quell fears about the health of the world's leading democracy. Later, Mr Trump said he was excited to begin carrying out an agenda to address immigration, health care and tax cuts. "So I have instructed my team to follow the example that President Bush's team set". A transition website, GreatAgain.gov, referenced 4,000 political appointee openings. Next month, Mr Obama's team plans to hold the first of two war-gaming exercises to prepare Mr Trump and his staff for a potential national security crisis. Donald Trump won 306 electoral votes to Hillary Clinton's 232 votes; however, as per the Associated Press, Clinton won the popular vote by about 300,000 votes (pending uncounted votes).
