The protesters are against a proposal allowing extradition to the Chinese mainland. Trump says he understands the reason for the demonstration, adding "I hope it all works out for China and for Hong Kong."
The issue has become a lightning rod for concerns over greater Chinese control and erosion of civil liberties in the semiautonomous territory. Trump gave his take Wednesday during a meeting at the White House with Polish President Andrzej Duda.
Hong Kong Chief Executive Carrie Lam blamed protesters for a politically motivated riot marked by violence and police force that followed a demonstration over a proposal allowing extradition to the Chinese mainland.
Lam noted that some young people in the crowd had expressed their views peacefully, but she condemned protesters who resorted to "dangerous and life-threatening acts."
Lam's comments in a statement Thursday suggested the peaceful protests that flowed through the city's streets on Sunday had devolved into a "blatant, organized riot."
Opponents of the extradition proposal say it could lead to an erosion of civil liberties in the former British colony.
The clash between protesters and police on Wednesday marked a violent new phase in the protest movement sweeping the semiautonomous Chinese territory.
Police fired beanbag rounds and rubber bullets while some protesters threw rocks and metal barricades. At least 72 people were taken to hospitals.

The authority said 10 remained in treatment, 19 were in stable condition, and 41 have been released.

Amnesty International has condemned what it called excessive force by Hong Kong police against largely peaceful protesters demonstrating against a proposed extradition bill, saying it violates international law and is likely to lead to worsening violence.
Amnesty International Hong Kong director Man-Kei Tam said tear gas and rubber bullets should never be used to disperse peaceful protesters because they are "notoriously inaccurate and indiscriminate, and can result in serious injury and even death."
The group warned that the police action was "fueling tensions and is likely to contribute to worsening violence, rather than end it."
A day of sit-ins and clashes between protesters and police on Wednesday marked a major escalation in the semi-autonomous city's biggest political crisis in years, fueled by concerns over growing Chinese control and erosion of civil liberties.
The German government says it is examining whether its existing extradition agreement with Hong Kong would be affected if a hotly contested extradition bill is approved in the territory.
The proposed bill would allow suspects in Hong Kong to be sent for trial in mainland China. It has prompted large demonstrations amid concerns over greater Chinese control and erosion of civil liberties in the semi-autonomous territory.
German Foreign Ministry spokeswoman Maria Adebahr said Wednesday that Berlin and its European Union partners have expressed their concern to Hong Kong authorities. She said "we are also examining whether the existing bilateral extradition agreement between Germany and Hong Kong could continue to be implemented in its current form if the planned extradition bill is approved."
Chancellor Angela Merkel's spokesman, Steffen Seibert, said it was a good sign that the majority of protesters have been peaceful "and we appeal to all concerned to ensure that things remain just as peaceful in Hong Kong."
Hong Kong Chief Executive Carrie Lam has spoken tearfully about the sacrifices she has made for the city in response to questions about whether she is "selling out" the territory by trying to push through a controversial extradition bill.
But in an interview with news channel TVB on Wednesday, Lam dodged questions about whether she would withdraw the bill in the face of chaotic and sometimes violent demonstrations against it by tens of thousands of angry residents.
Critics say the bill, which would allow suspects to be extradited to mainland China, could lead to an erosion of civil liberties in the semi-autonomous territory.
"It's time to let lawmakers with different opinions express their views under the legislative process," Lam said. "On whether to retract or push it through ... our consideration is this. There is no doubt this issue is controversial. Explanation and dialogue are useful but perhaps that has not entirely dispelled worries."
Speaking about her commitment to her job, her voice cracked as she said: "They said I'm selling out Hong Kong. How could I do that? I grew up here with everyone else in the city."
Lam added that she has never "felt guilty" over the issue and insisted she believed she was doing the right thing. She said she felt "worried and sad" about young protesters — many of them teenagers — on the streets, but said that as a parent to two sons, she believed it would be wrong to cave into young people's "willful behavior."
Hong Kong's legal community is urging the city's leader to withdraw a controversial bill that would allow suspects to be extradited to mainland China.
The Hong Kong Bar Association also said Wednesday it wants to know what the government's view is on principles underpinning the "surrender of fugitives" to the mainland following a New Zealand court case that stopped a man accused of killing a woman in Shanghai from being sent to China.
New Zealand doesn't have a formal extradition agreement with China and the case is considered an important precedent for Hong Kong, with which it shares a common law system from its roots as a British colony.
The association urged the government to "withdraw the bill for a full and proper consultation."
In a letter addressed to Hong Kong leader Carrie Lam, Chairman Philip Dykes said the group wants to know whether the government took into account the human rights situation in mainland China before seeking assurances from Beijing on the matter.

He says upholding the principle of "one country, two systems," as set out in the legally binding Sino-British Joint Declaration under which Britain returned Hong Kong to China, "is vital to Hong Kong's future success."

He said: "Hong Kong people's rights and freedoms have been fully guaranteed in accordance with law."
The protests have forced the delay of legislative debate over the bill, which would allow criminal suspects in Hong Kong to be sent for trial in mainland China.
Hong Kong's police commissioner says the scene around the city's government headquarters was "chaotic" and is appealing for protesters to leave the area.
