WASHINGTON, 20th January, 2017 (WAM) — Donald Trump was sworn in as the 45th president of the United States on Friday, succeeding Barack Obama in a transition of power that he has declared will lead to “America First” policies at home and abroad, Reuters reported.

As scattered protests erupted elsewhere in Washington, Trump raised his right hand and put his left on a Bible used by Abraham Lincoln and repeated a 35-word oath of office from the U.S. Constitution, with U.S. Chief Justice John Roberts presiding.

I, Donald John Trump, do solemnly swear that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States, so help me God, Trump said as he placed his hand on a family Bible and one used by Abraham Lincoln.

Trump was flanked by his family as past presidents, including outgoing president Barack Obama, and members of Congress and Supreme Court looked on.

The transition from a Democratic president to a Republican took place on the West Front of the domed U.S. Capitol before a crowd of former presidents, dignitaries and hundreds of thousands of people on the grounds of the National Mall. The crowd stretched westward on a cool day of occasional light rain.

The new president was to deliver an inaugural address lasting about 20 minutes centered on the campaign themes that he used in his November election victory over Democrat Hillary Clinton. Clinton attended the ceremony with her husband, former President Bill Clinton.

“It will be optimistic. It will be visionary, but it’s going to be philosophical,” his spokesman, Sean Spicer, said of the speech, speaking to NBC on Friday morning.

Trump and his vice president, Mike Pence, began the day attending a prayer service at St. John’s Episcopal Church near the White House.
