Trump becomes US president

A spokesman for former President George HW Bush, 92, says he and his wife Barbara, 91, son Neil, and daughter-in-law Maria were watching the inauguration ceremony from Houston Methodist Hospital in Texas. 

Mr and Mrs Bush were both admitted to hospital earlier this week due to dizziness and breathing issues. 

In a letter to President Trump, Mr Bush wrote that "my doctor says if I sit outside in January, it will likely put me six feet under".

"Same for Barbara. So I guess we're stuck in Texas," he wrote. 

His son, former President George W Bush, sat on the dais during the inaugural ceremony.

The website impeachdonaldtrumpnow.org has just gone live.

The organisers behind the campaign, Free Speech for People and RootsAction, cite Trump’s ownership of his luxury hotel and golf course businesses while in office.  

They allege this is a conflict of interest and an ethics violation.

Donald Trump: A list of potential conflicts of interest

As former President Obama speaks, Donald Trump signs orders for formal Cabinet nominations and a proclamation for a national day of patriotism, his spokesman says.

"Michelle and I have been really milking this goodbye thing," says Obama.

He says he and Michelle were just the "frontman and frontwoman" of the movement.

"Yes we did!" Obama says as he leaves.

Despite the naysayers, "all of you came together, in small towns and big cities, a whole bunch of you really young, and you decided to believe".

He praises those who campaigned for him and explained to their "parents how to pronounce Barack Obama".

"This has been the privilege of my life." 

Trump ally Roger Stone has taken to Twitter to air some grievances, and pat himself on the back.

Check out his top hat and three-piece suit.

"When we started on this journey, we did so with an abiding faith in the American people and their ability, our ability, to join together and change the country."

We knew that "change didn't happen from the top down, but the bottom up".

"Yes we did!" a crowd is shouting for Obama, as he lands at Andrews Air Force base. 

The former first couple are listening to the national anthem with their hands held over their hearts. 

New York Magazine editor Kyle Buchanan notes the background photo of the new Donald Trump presidential Twitter account - crowds waving flags in front of the Capitol building - is actually a photo from Barack Obama’s 2009 inauguration.

Some have noted that crowds were somewhat sparser at today's Trump swearing-in, compared with Obama's. 

Former veep Joe Biden is now travelling in somewhat less grander style.

He and his wife, Jill, have just boarded an Amtrak train which will take them to their home state of Delaware.

Biden, who served for decades as a US senator, famously liked riding the train into DC every morning, rather than live in the capital city itself.

The ride is just about two hours in each direction.

In the event of a disaster, one member of the president's cabinet always stays behind.

That person, who is known as the designated survivor, was Secretary of Homeland Security Jeh Johnson.

In the event of the worst, he would have wound up as the new US president.

Trump's inauguration ceremony was broadcast live to millions of people around the world.

Rather than using his new @POTUS Twitter account, the new president has used his @realDonaldTrump account to tweet segments from his inaugural speech.

Solidarity protests are going on across Canada.

Here are some images from the scene in Montreal. 

This from the Washington Post:

Trump’s speech was about 1,400 words versus about 2,400 for President Obama’s first inaugural speech. 

Obama’s second inaugural address in 2013 was about 2,100 words.

Obama and the former First Lady have just boarded a military helicopter which will take them to Andrews Air Force Base.

The chopper is called Executive One - not Marine One - since Obama is no longer president.

The Obamas will then will board a plane to California for a holiday.

The LA Times says the Obamas are headed to Sunnylands estate in Rancho Mirage, where the former president has taken several golf vacations and hosted foreign leaders over the past eight years.

As the former president departed, he shook hands with Trump and his wife, and also thanked his security detail 

Trump's reference to radical Islamic terrorism went down especially well with the crowd. The new president had consistently accused Obama of avoiding the term out of political correctness. 

Obama had retorted that he was reluctant to lump in militants with the more than a billion Muslims around the world.

These are the words Trump used most often during his speech.

Each word is given a size to indicate how frequently it was used.

It appears that "America" and "Americans" were some of the President's most often-used words.

The New Yorker takes an inauguration potshot at Trump's bombastic speaking style.

President Trump now has control of the official @POTUS Twitter account, including all of the followers it comes with.

How long until he uses his new megaphone?

The National Anthem was sung by 16-year-old former America's Got Talent contestant Jackie Evancho, accompanied by the US Marine Band. 

Her performance sounded like it was live. In 2013, Obama's last inaugural, Beyonce was criticised for lip-synching the national anthem in her performance. 

BBC reporters in the area say crowds are now repositioning themselves to try to get a view of Trump as he leads a parade back to the White House. 

The @FLOTUS account has also been turned over, passing from Michelle Obama to Melania Trump.

Michelle Obama is now tweeting from @FLOTUS44.

Trump had three clergy deliver invocations, and now he’s got three more for benedictions and scripture readings. Six is an inauguration record. Most have two, Nixon had five.

The rabbi, Marvin Hier, founded the Simon Wiesenthal Center in Los Angeles to fight anti-Semitism and bigotry. More than 3,000 people signed a petition asking him not to participate in this inauguration because they said Trump has only encouraged bigots.

Rabbi Hier stood by his decision. He is friendly with the family of Jared Kushner, Trump’s son-in-law and an Orthodox Jew. His family are big donors to the Wiesenthal Center.

As prayers continue, Reverend Franklin Graham tells the new president that the rain falling is a sign from above. 

A "we did it" congratulatory message from former KKK leader David Duke.

"Hear these words. You will never be ignored again," says Trump as he rises in a crescendo to finish with his signature promise.

"Together we will make America wealthy again.

"We will make America proud again.

"And yes, together we will make America great again."

"God bless America", he says twice before leaving the lectern. 

Obama seen mouthing: "Good job, good job."

"A new national pride will lift our sights and heal our divisions," says Trump. 

"It's time to remember that old wisdom our soldiers will never forget. That whether we are black or brown or white we all bleed the same red blood of patriots."

Here's snap analysis on Trump's speech by BBC correspondents. 

"We must think big and dream even bigger. l will no longer accept politicians who are all talk and no action, constantly complaining, but never doing anything abut it," Trump says.

"The time for empty talk is over, now arrives the hour for action. Do not allow anyone to tell you that it cannot be done."

"There should be no fear," Trump says before praising the nation's law enforcement and armed forces.

"Most importantly we will be protected by God" he tells the crowd.

"When you open your heart to patriotism, there is no room for prejudice"
