Donald Trump to meet Barack Obama at the White House today

President Barack Obama is set to welcome his successor, Donald Trump, to the White House. Mr Obama will be extending an olive branch to a man he has labelled unfit to serve as commander in chief and who led the charge to challenge the legitimacy of his own presidency.

The Oval Office meeting is the symbolic start of the transition of power from Mr Obama, a Democrat who ushered in a sweeping health care law and brokered a landmark nuclear accord with Iran, and Mr Trump, a Republican who has promised to wipe away those initiatives. Mr Trump takes office on January 20.
