Trump takes oath as 45th president of the United States
Donald Trump was sworn in as the 45th president of the United States Friday, taking the helm of a deeply divided nation and putting Republicans in control of the White House for the first time in eight years.
The billionaire businessman and former reality television star has pledged an era of profound change, energizing his supporters with promises to wipe away predecessor Barack Obama's signature achievements and to restore America to a lost position of strength.
But Trump's call for restrictive immigration measures and his caustic campaign rhetoric about women and minorities have infuriated other millions of Americans.
He assumes office as one of the most unpopular incoming presidents in modern history.
The pomp and pageantry of the inaugural celebrations were also shadowed by questions about Trump's ties to Russia, which US intelligence agencies have determined worked to tip the 2016 election to help the Republican win.
Trump's inauguration drew crowds to the nation's capital to witness the history. It repelled others. More than 60 House Democrats refused to attend his swearing in ceremony in the shadow of the Capitol dome.
One Democrat who did sit among the dignitaries was Hillary Clinton, Trump's vanquished campaign rival who was widely expected by both parties to be the one taking the oath of office.
Instead, it was Trump placing his hand on two Bibles, one used by his family and another used for President Abraham Lincoln's inauguration.

At 70, Trump is the oldest person to be sworn in as president, marking a generational step backward after two terms for Obama, one of the youngest presidents to serve as commander in chief.
