They fear the billionaire businessman’s political triumph will deal a blow to civil rights.

In the northwestern state of Oregon police said they detained 26 people as a protest turned violent in Portland. Demonstrators broke the windows of local businesses, lit firecrackers and started a fire in what police declared a riot.

It happened as several thousand people took to the streets in the city. Police said many in the crowd tried in vain to get anarchist groups to stop destroying property.

Police have deployed less lethal munitions such as OC spray and vapor (pepper spray), rubber ball distraction devices, rubber baton rounds.

Elsewhere, demonstrators blocked traffic in Minneapolis and Los Angeles. Denver in Colorado saw one of the largest protests. Hundreds marched in Dallas

In New York, a crowd chanted “we reject the president elect” and “not my president.”

While in Washington, protesters – mainly young people – took to a megaphone to voice their concerns.

“There’s a lot more of us than there are of them. Hillary won the popular vote, love does Trump hate. We need to continue this fight you guys, please,” said one demonstrator.

Another commented: “We’re going to make sure that Donald Trump knows how unhappy we are with the things that he has said and until he comes up and apologises and really stands to be a true American for all Americans, then he needs to step down”

A third protester added: “We’re a country of immigrants. We are a country of hard workers. And we are a country that has always benefited from the underdogs.”

Thursday’s demonstrations were generally smaller in scale and less intense than those the day before. But protesters are not giving up, with more anti-Trump action planned for the weekend.

The president-elect himself described the demonstrators in a tweet as professional protesters incited by the media.

In the morning Trump’s tone had changed to something more conciliatory, although the original tweet remained in place.

Just had a very open and successful presidential election. Now professional protesters, incited by the media, are protesting. Very unfair!

Love the fact that the small groups of protesters last night have passion for our great country. We will all come together and be proud!

Many opponents of the next president fear America’s values and cohesion are under threat. Donald Trump’s campaign was riddled with insults and claims that were exposed as lies.

But the millions who voted for him either didn’t care or had other deep-rooted reasons – and he won the race to the White House under the US democratic system.
