The Trumps are said to be running about 15 minutes late at this point leaving the service. They are emerging right now from St. John's church, and will travel by motorcade to the White House to meet the Obamas.
Outgoing President Obama was leaving the Oval Office for the last time, preparing for Trump's inauguration.
AFP reported:
Obama walked into the Oval Office holding a letter, which he placed on the Resolute desk -- a 19th-century desk used by many presidents.
It is customary for the outgoing president to leave a personal note for his successor. Obama was to have morning tea with Trump before they make their way to the Capitol for the inauguration ceremony.
President Obama, asked be reporters if he had any final words for the American people as he headed toward where he will greet the Trumps on their arrival at the White House, said, "Thank you."
President-elect Trump and his wife are reportedly preparing to leave St. John's church following the prayer service.
They will be driven the short distance to the White House, where outgoing President Barack Obama and his wife, Michelle, await them.
Here is one of outgoing president Barack Obama's goodbye tweets.
Reuters on the historical effects of U.S. inaugurations on financial markets and the dollar:
For financial markets, the Trump era begins on Monday, and if history is any guide the following month should be a rocky one for Wall Street but positive for the dollar.
The S&P 500 has fallen a median 2.7 percent in the month after each new president has taken the keys to the White House since Herbert Hoover did so in January 1929, according to Reuters analysis.
Only four presidents have seen Wall Street rise in their first month in power: Hoover (+3.8 percent), John F. Kennedy in 1961 (+6 pct), George H. W. Bush in 1989 (+5.3 pct) and Bill Clinton in 1993 (0.8 pct).
The market has fallen in the first month under every other incoming president since Hoover. Even Ronald Reagan and Barack Obama, who ultimately presided over 120 percent and 165 percent rallies on Wall Street during their two terms, respectively, saw initial slides of 4.8 percent and 15 percent.
The dollar tends to fare better. Analysis going back to the early 1970s when the currency was taken off the gold standard shows it has risen an average 2.2 percent in the first month of a first-time president.
U.S. Vice President-elect Mike Pence's first tweet of the day also quotes Trump's earlier tweet.
Russian President Vladimir Putin's spokesman Dmitry Peskov told Russia's Vesti On Saturday program in a fragment that was released early today, seemingly to underscore a perception of parity between Russia and the United States:
"It cannot be without differences and disagreements. [Russia and the United States] are indeed the two largest countries in the world and we can't coexist without tensions, without conflicts. And the success of bilateral relations will depend on how much is based on dialogue and not on open confrontation, as it was for the last few years. We will be able to move toward resolving those differences."
BBC has tweeted a poll by the Pew Research Center, saying that 86 percent of Americans describe the United States as more politically divided today than ever before.
