President Barack Obama held his first news conference since Republican Donald Trump won election to succeed him.

The session with reporters on Monday focused on questions about the election, its consequences for U.S. policy and Obama's own legacy.

Obama then departs on his last overseas trip as president. The weeklong tour was planned when it seemed certain Hillary Clinton would win the contest and was designed to reassure the world that the U.S. had regained its footing after a toxic campaign.

Obama will instead likely try to use the trip to calm world leaders about what comes next as trump prepares to take over as president.

The president says he can reassure allies of the united states that his successor supports NATO. He says on the weeklong tour of Greece, Germany and Peru, he'll relay Donald Trump's ``commitment to NATO.'' As a candidate for president, Trump complained that other members of the treaty organization did not contribute enough for the protections it affords.

Obama said the reassurance is ``one of the most important functions'' he can serve during the trip.

Also during Monday's news conference, the president reflected on Democrat Hillary Clinton's loss to President-elect Donald Trump in last week's election.

He also reflected on his own campaign for president eight years ago, recalling all of the time he spent in Iowa to win that state's lead-off caucuses. He said he won the state because he spent time going everywhere, meeting everyone.

He stresses that Democrats ``have to compete at a grass roots level.''

Clinton spent much of her time and money campaigning in swing and Republican-leaning states in the late stages of the 2016 campaign, losing several states that had consistently voted Democratic in the past several presidential elections.

President Obama says he urged his successor to immediately turn his focus to finding qualified people to staff his White House.  President Obama offered some details about the meeting he had last week with Donald Trump.  He said he offered trump honest advice in a lengthy conversation and highlighted the importance of finding trusted aides.  He stressed the need to give Trump the ``rope and space'' for a ``reset.''    The president also reflected on his own arrival in the white house during the midst of the economic crisis. He says Trump will have more ``time and space'' to make ``judicious decisions.''
