Thousands of demonstrators took to the streets in several US cities for a second night of nationwide protests over the stunning election of Donald Trump to the presidency.
Trump, commenting on the unrest for the first time, blamed the news media.
Shouting "Not my president!" and carrying placards that read "I did not elect hate for president", some 300 people marched in Baltimore, AFP reported.
Protests also took place in New York, Chicago, Denver, Dallas, Oakland and elsewhere.
Trump commented on the protests saying in a tweet: "Just had a very open and successful presidential election. Now professional protesters, incited by the media, are protesting. Very unfair!"
Protesters Ready for 4 Years of Resistance
Hours later he seemed to change tack, writing, "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!"
The violence stood in contrast to an apparently harmonious meeting between Trump and President Barack Obama designed to heal divisions after the most acrimonious election campaign in recent memory.
Obama and Trump put past animosity aside during the 90-minute White House meeting designed to quell fears about the health of the world's pre-eminent democracy, and vowed to carry out a smooth transfer of power.
After a nasty campaign that culminated in the election of a 70-year-old billionaire and former reality TV star who has never held public office and who gained power on a populist platform, the message was: This is business as usual in a democracy.
The outgoing Democratic president and his successor huddled one-on-one in the Oval Office, for what Obama characterized as an "excellent conversation" and then put on a remarkably civil joint public appearance.
"It is important for all of us, regardless of party and regardless of political preferences, to now come together, work together, to deal with the many challenges that we face," Obama said.
How far this sentiment will resonate and be reciprocated remains to be seen.
"We are just showing that this is going to be the next four years. It'll be four years of resistance," Kaila Philo, a 21-year-old student, told The Baltimore Sun.
- Not My President!
On Portland, police said a rally there had degenerated into what they called a riot because of "extensive criminal and dangerous behavior". Police said protesters were smashing storefront windows.
Earlier on Thursday, demonstrators—mostly students who skipped classes—also marched in San Francisco, Los Angeles and other cities.
Some 1,000 students, most of them high-schoolers, marched through San Francisco's financial district toward City Hall chanting "Not my president!" and blocking traffic. Some also carried placards that read "Trans Against Trump" and "Make America Safe For All."
Students held walkouts in several other northern California cities, including Napa and Hayward.
In Los Angeles, several hundred students marched at the University of California campus carrying placards that read "Dump Trump" and "Love trumps hate."
In New York, some 300 to 400 anti-Trump protesters gathered, down from 2,000 the day before. Police kept them on the sidewalk and prevented them from blocking Fifth Avenue.
Similar demonstrations that attracted tens of thousands of people took place in various cities on Wednesday.
