In President Trump's telling of it, Portland, Ore., is a city under siege by violent radical leftists. He has suggested that only the strong hand of federal law enforcement can save it.

On Fox News this week, Acting Homeland Security Secretary Chad Wolf admonished state and local leaders there and elsewhere for failing to restore law and order, and he touted the administration's response.

"We've seen about 300 arrests across this country regarding civil unrest and protest, violent protesting, I'd say criminal protesting, criminal rioting," Wolf said. "About 100 of those have been in Portland specifically, and I know the Department of Justice has charged about 74 or 75 individuals in Portland there with different federal crimes."

But an NPR review of the federal cases brought in Portland shows that the majority of the charges are for what could be considered minor offenses.

As of Aug. 28, the U.S. Attorney's Office for Oregon had charges outstanding against 74 people in connection with the Portland unrest.

Of those cases charged, 11 are for citations and 42 are for misdemeanors, meaning that more than 70% of the total charged cases are not felonies.

"A citation is the least serious of a charge, it's really more of a ticket," said Lisa Hay, the federal public defender for Oregon.

The misdemeanor cases are almost evenly divided between class A and class C misdemeanors.

A class C misdemeanor is one step above a citation and is punishable by no more than one month in jail. In Portland, at least 19 people face class C misdemeanor charges for allegedly failing to comply with a lawful order.

"That might be somebody who's in front of the federal courthouse, on the sidewalk, and an order is issued to disperse, and they didn't disperse or they didn't move away quickly enough," said Hay.

The class A misdemeanor cases in Portland have typically involved an alleged assault of a federal officer but without physical contact. Such a case could involve, for example, verbally abusing an officer or pretending to throw an object.

These sorts of misdemeanors are punishable by no more than one year in prison.

Steve Kanter, a law professor and former dean at Lewis and Clark Law School in Portland, said the federal government's decision to arrest and charge people for offenses like failing to comply with a lawful order suggests that law enforcement officer were acting in a selective manner "to control and chill expression and activity."

"There should be a clear dividing line between people who are trying to get their voices heard, fully protected by the First Amendment and the right to assemble," he said, "and people that engage unjustified violence against persons or property."

Kanter said those who engage in violence — and he made clear that there have been people in Portland doing exactly that — should be prosecuted.

The vast majority of the protesters in the city have been nonviolent, but some demonstrators have set fires, thrown projectiles and, in some instances, attacked federal officers.

After Trump sent a surge of federal law enforcement to Portland in July, the area around the federal courthouse downtown for weeks was a battle zone at night as some protesters clashed with federal agents guarding the facility.

Federal prosecutors have brought more serious felony charges against those they say engaged in the violence — 20 cases as of late last week, according to NPR's review of the court papers.

Those are primarily either assault of a federal officer or arson charges. One defendant, for example, is accused of hitting a deputy U.S. marshal with a hammer, while another allegedly struck a deputy U.S. marshal with a baseball bat.

The president and Attorney General William Barr have repeatedly blamed what they call left-wing radicals and members of the antifa movement for the violence in Portland and elsewhere.

"I've talked to every police chief in every city where there's been major violence, and they all have identified antifa as the ramrod for the violence," Barr told CNN this week.

"They are flying around the country We know people who are flying around the country," Barr said. "We see some purchases they are making before the riots of weapons to use in those riots."

None of the court documents from federal cases in Portland reference antifa or any sort of broader anti-fascist movement or conspiracy.

In a few of the case files, there are references to apparent agitators. For instance, one defendant told authorities that he was handed a firework by a masked person in the crowd and told to throw it.

But there is nothing more substantial in the federal court record in Portland at this point to support the attorney general's assertions.

In the public record, the man suspected of fatally shooting a right-wing activist in Portland last weekend said he supports the anti-fascist movement but is not a member of it.

The man, Michael Reinoehl, was killed Thursday night as law enforcement officers tried to arrest him.
