The city in one of the most significant states of the electoral map has been in turmoil since the shooting by a white police officer of an African American man in front of his children during an arrest this month.
"The people of Portland, like all other cities & parts of our great Country, want Law & Order", the president wrote. With about nine weeks until Election Day, some of his advisers see an aggressive "law and order" message as the best way for the president to turn voters against his Democratic rival, Joe Biden, and regain the support of suburban voters, particularly women, who have abandoned him.
Democratic presidential nominee Joe Biden will accuse President Donald Trump in a speech delivered from battleground state Pennsylvania on Monday of sowing chaos rather than providing order on racial issues, the coronavirus and the economy.
On Tuesday, Trump plans to visit the city of Kenosha in Wisconsin, where protests are continuing over the police shooting of a 29-year-old black man. He also pilloried Trump for playing "such a subservient role" to Vladimir Putin in refusing to address bounties the Russian government placed on USA troops. I have never been a fan of, 'We all wear pink on Wednesday, ' we all have to do this, we all have to say this.
"I want to be very clear about all of this: Rioting is not protesting. So when you are encouraging criminals and anarchy, people's lives are lost", Republican Sen.
"Do you really feel safer under Donald Trump?"
Biden condemned the violence and argued that Trump had played a role in spurring the clashes.

The demonstrations were primarily peaceful, though some police officers were attacked and several people arrested. About 18,000 people took part in Saturday's march, police said.
Trump, who appeared to be watching, responded with real-time tweets labeling Wheeler a "wacky Radical Left Do Nothing Democrat". "I am not banning fracking, no matter how many times Donald Trump lies about me", Biden said during a speech in western Pennsylvania, home to one of the largest natural gas deposits in the world.
If elected, his administration would work to "lower the temperature" of the country with "less divisive" rhetoric, eliminating a presidency that has been a "toxic presence for four years" and has poisoned how Americans talk to one another and democracy itself, Mr Biden said.
Speaking in the battleground state of Pennsylvania, Mr Biden said the USA was facing multiple crises, which "under Donald Trump, keep multiplying".
"The big backlash going on in Portland can not be unexpected after 95 days of watching and incompetent Mayor admit that he has no idea what he is doing", Trump said in one Twitter post.
Saturday's shooting during a pro-Trump rally in the OR city followed a week of countrywide protests over the police shooting in Kenosha, Wisconsin, of African American Jacob Blake. In a subsequent protest, two demonstrators were shot and killed and a third wounded; a 17-year-old has been charged with homicide.
Biden's trip to Pennsylvania comes amid national protests in response to police violence and the recent police shooting of Jacob Blake in Kenosha, Wis.
Asked whether the president would condemn the actions of the teen suspect, White House press secretary Kayleigh McEnany declined to weigh in at a press briefing Monday. "We are facing multiple crises - crises that, under Donald Trump, keep multiplying".
