One of the biggest crowds gathered outside 58-storey Trump Tower in New York on Friday. This was the third night of protests since Trump’s election on Tuesday night, CNN reported.
More demonstrations are expected through the weekend, according to authorities.
In Miami, hundreds of people walked down Biscayne Boulevard chanting “Love Trumps Hate” and carrying signs with messages such as “How many judges will it take to ruin America?”.
Much of the group walked onto Interstate 395 and surrounded cars. Four lanes of traffic came to a standstill.
Interstate 80 in Iowa city was shut down briefly by about 75 protesters, Sgt. Chris Akers with the Iowa City Police Department said. However, no one was arrested, CNN said.
Trump tweeted twice about the protests. On Thursday he said, “Just had a very open and successful presidential election. Now professional protesters, incited by the media, are protesting. Very unfair!”
On Friday he said: “Love the fact that the small groups of protesters last (Thursday) night have passion for our great country. We will all come together and be proud!”
Protests occurred in many other cities, including in New Haven, Connecticut; Orlando, Florida; Chicago; Boston; Asheville, North Carolina; Vanderbilt University in Nashville, Tennessee; Ohio State University in Columbus; and high schools in Denver and Omaha.
The groups were angry about policies Trump has promised to enforce concerning immigration, the environment, LGBT rights and other issued.
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, city officials appealed on Friday for calm after a Thursday night protest by about 4,000 people turned violent. Windows on businesses were broken and a car dealership was vandalised. Twenty-five people were arrested, CNN noted.
In Boston, hundreds of people gathered in Boston Common — central public park — for a “Love Rally in the Common”.
Organisers said on Facebook: “Let’s unite together to peacefully show all of those whom Donald Trump or his supporters have put down that we still care about them, and to give them an opportunity to have their voices be heard.”
A similar rally was held in Washington Square in New York, the Facebook page said. “Spread love and peace through the country, and help start the movement #LoveStillTrumpsHate”, CNN added.
