Trump inauguration

At its peak, a record 8.7Tbps of live video was streamed, according to content delivery network Akamai Technologies.

The previous record of 7.5Tbps was set during US election day coverage on 8 November 2016.

The figures reflect the growing popularity of online streaming.

In the US, 31 million people watched Mr Trump's inauguration on television, compared with 38 million who watched Barack Obama becoming president in 2009.

However, video traffic of Mr Obama's inauguration reached a peak of just 1.1Tbps the same year.

"I just got the impression when he was speaking there, that somehow, he forgot that he was President of the United States and was speaking to the intelligence officers that spend their lives trying to serve this country. That was not the appropriate place to start whining about what was happening in terms of numbers in the inauguration," Panetta told CNN's Wolf Blitzer on "The Situation Room" Monday.

In an interview on NBC's "Meet the Press," host Chuck Todd pressed Trump senior adviser Kellyanne Conway about why the White House on Saturday had sent Spicer to the briefing podium for the first time to claim that "this was the largest audience to ever witness an inauguration, period."

"You're saying it's a falsehood. And they're giving -- Sean Spicer, our press secretary -- gave alternative facts," she said.

He said the crowd had reached the Washington monument as he spoke at the US Capitol, despite photographic evidence to the contrary.

Later, his White House press secretary said it had been "the largest audience to ever see an inauguration, period".

On Saturday, millions in the US and around the world protested against Mr Trump's new administration.

Video posted online by the outlet shows the white supremacist speaking to Washington bureau chief Zoe Daniel when he was interrupted by individuals off camera.

Spencer was answering questions on whether he was a neo-Nazi. He said he was not, and was then asked what the "Pepe the Frog" pin he was wearing signified.

"Pepe the Frog" is an internet meme so often used by racists and anti-Semites it was designated a hate symbol by the Anti-Defamation League.

He spoke of abandoned factories, rampant crime and a failed education system, pledging that his presidency would bring about change.

"This American carnage stops right here and stops right now," President Trump said on the steps of the Capitol.

Thousands of Trump supporters travelled across the country to witness the occasion from the National Mall.

The moment marks the end of an improbable journey for the property tycoon after a campaign marked by controversy.

There has been speculation since the star told a concert crowd he would have voted for Mr Trump - if he had voted - and then turned up at Trump Tower.

But Tom Barrack, the Presidential Inaugural Committee chair, told CNN the ceremony is "not the venue" for West.

Speaking on the steps of the Lincoln Memorial in Washington DC, the president-elect also promised to bring change.

Among attendees at the two-hour event were his family, actor Jon Voight and Soul Man singer Sam Moore.

Mr Trump earlier laid a wreath at Arlington National Cemetery, Virginia.

Thursday evening's Make America Great Again! Welcome Celebration was open to the public and featured performances by country stars Toby Keith and Lee Greenwood.

"We're going to unify our country," Mr Trump said in brief remarks at the end of the concert.

But for many people in the US, it's not been a popular move.

The Make America Great Again! Welcome Celebration takes place on Thursday evening before Donald Trump is sworn into office.

For Barack Obama's inauguration concert in 2009 - Bruce Springsteen, Stevie Wonder and Beyonce all played.

Donald Trump's line-up doesn't quite hit those highs, but Chrisette Michele is someone who stands out on the list.

"We haven't asked him," he told CNN's Erin Burnett on "OutFront." "He considers himself a friend of the President-elect, but it's not the venue. The venue we have for entertainment is filled out, it's perfect, it's going to be typically and traditionally American, and Kanye is a great guy but we just haven't asked him to perform. We move on with our agenda."

Last month, sources told CNN the transition team was struggling to book big names for the inauguration. Boris Epshteyn, an inaugural committee spokesman, also noted the lack of A-listers appearing at the ceremony.
