Thousands took to the streets of cities across the US late Friday and early Saturday as anti-Donald Trump protests saw highways and interstates blocked, numerous arrests - and a shooting at a march in Portland, Oregon.

Angry crowds gathered once again outside the 58-story Trump Tower, the President-elect's home in New York, reported CNN.

Protester Shoshi "Rabin" Rabinowitz explained her motivation for being there: "Words can't describe how disgusted I am that he was elected over Hillary (Clinton)," she said.

There have been nightly protests since Trump's election and more demonstrations are expected through the weekend.

Trump has tweeted about the protests. On Thursday night he said, "Just had a very open and successful presidential election. Now professional protesters, incited by the media, are protesting. Very unfair!"
 
He was more conciliatory Friday morning, saying: "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!"

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!

On Friday protests were held in several cities including Los Angeles, New Haven, Connecticut; Orlando, Florida; Chicago; Boston; Asheville, North Carolina; Nashville, Tennessee; Columbus, Ohio; and at high schools in Denver and Omaha.

Arrests were made in Los Angeles -- but the police department was not able to immediately provide the number of people arrested.

Groups in that city and elsewhere across the country are angry about policies Trump has promised to enforce concerning immigration, the environment, LGBT rights and other issues.

The Facebook page for a protest planned in Burlington, Vermont, said: "Come protest the xenophobia, racism, homophobia, misogyny,and climate science denial of the Trump/Pence regime!! Come show your support for our Muslim, queer, immigrant, and female family!!"

In Portland Oregon, a man was injured in a shooting on the Morrison Bridge during a protest march early Saturday morning.

Protesters also blocked the street outside Portland's City Hall on Friday. As the sun set on the crowd, police tried to disperse the protestors but tensions remained high.

Earlier in the day, city officials appealed for calm after a Thursday night protest by about 4,000 people turned violent. Windows on businesses were broken and a car dealership was vandalized. Twenty-six people were arrested, said the report.

"We had some anarchists who hijacked that event and did terrible damage to our neighbors and friends," Mayor Charlie Hales said at a news conference. "They spread violence and fear and detracted from the legitimate exercise of those First Amendment rights."

In Boston, hundreds of people gathered on Boston Common for a "Love Rally in the Common."

In Miami, hundreds of people walked down Biscayne Boulevard chanting "Love Trumps Hate" and some protesters even walked onto Interstate 95 and surrounded cars, forcing four lanes of traffic to a standstill.

In Atlanta, an American flag was burned near the Georgia State Capitol building, something that didn't please protesters Sanjay Mendonca and Akshita Mendonca. Aged 40 and 39, respectively, they voted for Hillary Clinton.

"The current situation is not good for us and our children," Sanjay said. "I'm here for my kids because I don't want them to think we didn't do something ... A lot of people feel hopeless right now."
