Dark is falling on the US east coast, and protesters are starting to leave the demonstration area. 

Washington DC police refuse to give an official count for how many people turned up today. So we're unlikely to know exactly how many people turned out in the nation's capital.

But it's clear there were more people on the streets of DC today than when Trump was sworn in as president yesterday.

Hundreds of thousands, if not millions, also staged protests against Trump in more than 600 cities and towns around the world. 

Meanwhile, Trump visited the CIA headquarters where he assured America's spies he was fully behind them, before disputing media accounts of crowd figures and the weather on Friday.

As President Donald Trump was returning from a visit to the CIA headquarters in Virginia, protests continued in Washington DC and around the US. 

Reporters travelling in Trump's motorcade filmed his view during the car journey. 

As he walked back into the White House, the protests were clearly audible.  

Canadian Prime Minister Justin Trudeau spoke with President Donald Trump on Saturday, according to the prime minister's office.

The two men discussed trade and other elements of the bilateral relationship.

"The Prime Minister noted the depth of the Canada-US economic relationship, with 35 states having Canada as their top export destination. The Prime Minister and the President looked forward to meeting soon," said a press statement.

Trudeau also spoke with Trump after his election win in November, during which the prime minister extended an invitation for the new president to visit Canada.

It has become tradition for new US presidents to come to Canada for their first foreign visit.

A writer for Saturday Night Live has been catching some flak for a tweet mocking Barron Trump, the 10-year-old son of the US president and first lady.

Katie Rich tweeted that Barron was going to grow up to become America’s "first homeschool shooter". She deleted it three hours later.

More vignettes from DC...

About 50,000 people marched through the streets of Toronto, one of the many women's marches taking place all over Canada. Despite the big crowds, the protest was calm and orderly, a sign of Canadian "politeness", said marcher Kaila Mintz.

Although most people were there to protest against Trump, the issues of women everywhere were top for many, and speakers specifically applauded the organisers of Black Lives Matter for helping to reinvigorate political protest in the city and the world.

"It's quite great to see all the different groups coming together here, it's not divisive at all," Mintz said.

But Canadians shouldn't gloat, said protester Sophie Jaworski.

"It's happening in the Canadian context," she said.

Many in the crowd carried signs demanding an end to violence against indigenous women, and equal pay for equal work.

"I think it's important to bring attention to real issues, when there's so much distraction and fake news in politics going on," Jaworski said.

A woman who attended the civil rights protest in 1963, known as the March on Washington for Jobs and Freedom, returned today for another historic protest.

"My daughter is going to remember this for the rest of her life. Because of this new administration, I think it's important for me personally to stand up for the rights of women." - John Philbeck

"I am here for me and I am here for my daughter because I want the world that she inherits to be a better one than I had." - Jennifer

Can you spot what looks like a very British penchant for understatement in one of these signs from the London march?

Representative John Lewis, a civil rights veteran who recently provoked the ire of Trump, was among the speakers at the Atlanta march

Mr Lewis, the last surviving speaker from the 1963 March on Washington, led by Martin Luther King, refused to attend the inauguration on the grounds that he did not see Mr Trump as a legitimate president.

"I think the Russians participated in helping this man get elected," he had told NBC's Meet the Press. "And they helped destroy the candidacy of Hillary Clinton."

In turn Mr Trump attacked Mr Lewis, claiming his district was in "horrible shape" and that he was he was "talk, talk, talk  - no action or results".

Dozens of Democratic representatives backed up Mr Lewis, refusing to attend the inauguration.

Trump disputes reports that he replaced a bust US civil rights leader Martin Luther King Jr with one of Britain's wartime leader.

"In the Oval Office there's a beautiful statue of Dr Martin Luther King. And I also happen to like Churchill. Winston Churchill. I think most of us like Churchill."

"He doesn't come from our country," Trump shrugs. "Helped us. Real ally."

He digresses to point out that he's been on the cover of Time magazine "the all-time record... 15 times this year", adding that this is more than even NFL star Tom Brady.

Trump says Time erroneously reported that he had removed the bust of Dr King.

"I would never do that because I have great respect for Dr Martin Luther King," he adds.
