Protests sparked by the killing of George Floyd in Minnesota last week continued to intensify across the U.S. Sunday, as protesters broke local curfews to voice frustration over policing in America.
In Minneapolis, a semi-truck was seen barreling toward a massive group of demonstrators on an interstate, though no protesters appear to have been injured in the incident.
Some elected leaders have blamed the violence that has broken out at some protests on organized extremists, though so far they have offered little evidence to support their claims.
President Donald Trump said Sunday that he would designate the radical lefitst group antifa a terrorist organization after earlier attributing the violence to “thugs” who he said were “dishonoring the memory of George Floyd." The comment drew criticism from Keisha Lance Bottoms, the Democratic mayor of Atlanta, and Sen. Tim Scott, R-S.C, the Senate’s lone black Republican.

ANALYSIS: Trump envisioned 'American carnage.' Now, he's got it.

WASHINGTON — American carnage isn't just one of President Donald Trump's catchphrases anymore.
When Trump first addressed the nation as its president on Jan. 20, 2017, he depicted the nation's cities as domestic combat zones and declared "this American carnage stops right here and stops right now."
Back then, it was hyperbole at best. But it's become reality on his watch, and he has encouraged further violence.
More than 100,000 Americans have lost their lives, and another 40 million have lost their livelihoods, amid a coronavirus pandemic to which Trump was slow to react. Against that backdrop, cities across the country are now combustible cauldrons of fear, anger, fire and tear gas as Trump has responded to the violence with threats and little evidence of understanding its cause.

Opinion: George Floyd couldn't breathe. We protest because now all of Black America can't either.
George Floyd should have been alive today. George Floyd would have been alive today if his humanity was recognized, valued and respected. George Floyd should have been protected by those who swore an oath to uphold the law and help the communities they serve. George Floyd is no longer with us because even in the middle of a global pandemic, police brutality has not ceased, writes Rev. Al Sharpton for NBC News THINK.
COVID-19 is ravaging us, making it difficult to breathe, and yet systemic racism has been tightening its grip on our throats for years, Sharpton writes. Racism is trauma, passed from generation to generation. Enough is enough.
Trump says he will designate Antifa a terrorist organization as GOP points fingers at extremists
President Donald Trump tweeted that he was designating Antifa as a terrorist organization.
That followed Trump and Attorney General William Barr earlier pointing to anti-fascist organizers and anarchists as culprits behind the violent protests following the death of George Floyd, a 46-year-old black man, at the hands of Minneapolis police.
Others said right-wing extremists such as Boogaloo followers, who hope to bring about a second Civil War, were pushing for such uprising in the protests.
Illinois activates National Guard after protests leave six shot, one dead
The Illinois National Guard has been activated to “support” Chicago amid continued protests that led to 240 arrests, six people shot and one death, the Illinois governor and Chicago mayor announced on Sunday.

Minnesota governor praises peaceful protesters, more than 50 arrests in Minneapolis area
Gov. Tim Walz on Sunday morning commended peaceful protesters in Minnesota as a celebration of diversity, even as the state reconciles with the destruction that occurred overnight with more than 50 arrested by the early hours of the morning.
"The beautiful expression of solidarity and community that we saw played out by peaceful protesters, by that beautiful tapestry that is Minnesota," Walz said. "Indigenous dancers leading in the middle while the crowed kneeled around in reverence in making sure that justice was served."
Minneapolis Mayor Jacob Frey on Sunday noted that the violent incidents Saturday happened alongside joyous protests of people "rallying around a common cause, which is each other," and communities coming out together to clear the debris in the morning.
"Even though the whole world has seen us at out worst, we can still be at our best," Frey said.
About 25 people were arrested in Hennepin County and another 30 in Ramsey County by 2 a.m., Minnesota Public Safety Commissioner John Harrington said Sunday. More arrests were made between then and about 6 a.m., but Harrington did not have an exact count.

Mayor Bill de Blasio announces probe after video shows NYPD SUVs driving into protest crowd
New York City Mayor Bill de Blasio on Sunday announced an investigation into a video appearing to show a New York Police Department cruiser driving into a crowd of protesters. The announcement came a day after De Blasio defended the alleged police action caught on camera.
"I didn't like what I saw one bit. I did not want to ever see something like that, I don't want to ever see it again," de Blasio said. "And clearly, we need to do a full investigation and look at the actions of those officers and see what was done and why it was done and what could be done differently."
The mayor announced the launch of an independent review into the video led by Corporation Counsel James Johnson and New York City Department of Investigation Commissioner Margaret Garnett. The results are expected to come in during the month of June, he said.
Still, de Blasio chastised protesters, calling their tactic of surrounding police vehicles dangerous.
Protests and National Guard response draw comparisons to unrest in 1968
As of Saturday at least 10 states had called up the National Guard to enforce curfews in cities around the country. The decision mirrors that of state leaders in 1968 when multiple cities erupted in civil unrest following the assassination of Martin Luther King Jr. in Memphis.
National Guard troops were also called into action in California in 1992, after a jury’s decision to acquit the police officers caught on tape beating black motorist Rodney King.
While the Watts Riot in 1965 was sparked by police action, it’s the multi-city uprisings that followed the assassination of Martin Luther King Jr. in 1968 that represent the most direct comparison, said Gerald Horne, author of the book, “Fire This Time: The Watts Uprising."
But even then, people were relatively optimistic, or had reason to be, about the federal government, he said. This time, some of those who have taken to the streets have focused their ire on the buildings and institutions that represent power, Horne said. That includes police stations in Minneapolis, a state house in Ohio, several Trump hotel properties and, last night, the White House.
"That is quite remarkable,” said Horne, who is also a professor of African American studies at the University of Houston. “That makes me worry about what is going to happen tonight. These are direct challenges to the power of the state, a state that has operated in grossly unjust ways but a challenge."
D.C., Atlanta mayors call for calm, say 'solution is not to destroy our cities'
WASHINGTON — Amid nationwide protests sparked by the death of George Floyd while in custody of a Minneapolis police officer, the mayors of two major cities Sunday urged those participating to remain peaceful, calling the destruction of property something that's not a productive solution to the frustrations.
“We’re sending a very clear message to people that they have a right to exercise their First Amendment rights, but not to destroy our city," Washington D.C. Mayor Muriel Bowser said in an exclusive interview on "Meet the Press."
"We saw a level of just destruction and mayhem among some that was maddening.”
Target to close 175 stores amid protests

The Minneapolis-based chain said in a statement Sunday it was heartbroken by the death of George Floyd and the pain his death has rippled through communities around the country. Stores closing include more than 30 locations in Minnesota and dozens in states such as California, Illinois and New York.

NYPD Commissioner decries 'mob' out to co-opt equality movement
NYPD Police Commissioner Dermot Shea on Sunday morning denounced the "willful destruction of property" in New York City in a Twitter thread.
Shea praised officers in his statement and denounced those who he said were not out to protest police brutality, but were a "mob" that wished to co-opt the death of George Floyd to inflict harm.
"What it was, quite frankly, was a mob bent solely on taking advantage of a moment in American history, to co-opt the cause of equality that we all must uphold, to intentionally inflict chaos, mayhem, and injury just for the sake of doing so," Shea tweeted.
Netflix, Amazon, Hulu say black lives matter
Netflix, Amazon, Hulu and other major Hollywood players are using their corporate social media accounts to take a stand and support the Black Lives Matter movement, amid nationwide protests decrying the police killing of George Floyd.
Netflix tweeted on Saturday: "To be silent is to be complicit. Black lives matter. We have a platform, and we have a duty to our Black members, employees, creators and talent to speak up."
While, CEO of ViacomCBS-owned Paramount Jim Gianopulos sent an internal memo to employees, expressing that "too many members of the Black community have had their breath stolen from them through racial injustice."
Alphabet-owned YouTube on Friday also posted that: "We stand in solidarity against racism and violence. When members of our community hurt, we all hurt. We're pledging $1M in support of efforts to address social injustice."
Thousands gather at London protest
Thousands gathered in London’s Trafalgar Square to express their outrage over the death of George Floyd on Sunday, as demonstrators clapped and waved placards as they offered support to U.S. protestors.
The crowd gathered despite U.K. government rules barring large crowds gathering because of the COVID-19 pandemic.
Social media posts show a number of protests have been planned for the coming week in the U.K.’s capital city.
Even so, the protests do not originate from the official Black Lives Matter U.K. group, which said on Twitter that while the coalition "stands in solidarity with all those whose hearts feel broken," it is still "discussing the implications of calling a mass march in the middle of a pandemic that is killing us the most."
At least 27 protesters arrested on Saturday night in Seattle
At least 27 people were arrested while protesting in Seattle on Saturday night, the city's police chief said in a news release Sunday.
The alleged offenses varied from assault to arson, destruction and looting, Chief Carmen Best said.
“In the aftermath of the murder of George Floyd we all are rightfully angry, sad, frustrated, and heartbroken,” Best said.
She added that while the protest began peacefully at noon on Saturday, they became increasingly violent as the afternoon went on, "due to the actions of some groups who wanted to take advantage of this situation."

The tweet also featured a screenshot of U.S. Secretary of State Mike Pompeo's statement from 2018, addressing protests in Iran, but with elements crossed out and replaced to include references to the ongoing protests in the U.S.
U.S. police failing to respect right to peaceful protest: Amnesty International
U.S. police across the country are failing their obligations under international law to respect and facilitate the right to peaceful protest, rights group Amnesty International warned Saturday, adding that this was exacerbating a tense situation and endangering the lives of protesters.
“In city after city, we are witnessing actions that could be considered unnecessary or excessive force," said Rachel Ward, national director of research at Amnesty International USA. "We call for an immediate end to any excessive use of force and for law enforcement to ensure and protect the legal right to protest.”
She added that the use of heavy-duty riot gear and military-grade weapons and equipment to police largely peaceful demonstrations may intimidate protesters who are practicing their right to peaceful assembly.
“Equipping officers in a manner more appropriate for a battlefield may put them in the mindset that confrontation and conflict are inevitable,” she said.
Crowds hit with tear gas in Las Vegas
LAS VEGAS — Demonstrations appeared to get rowdier in downtown Las Vegas Saturday as the night unfolded.
Shortly before 10:30 p.m., many demonstrators set off fireworks near the federal courthouse on Las Vegas Boulevard. About a block down the same street, a group of looters appeared to break into a pawn shop.
Demonstrators in other locations reported that police cars windows were being smashed. Police officers in riot gear rushed down the streets, setting off flash bangs. Officers released tear gas into the air.
"I’m a peaceful protester and I don’t know why I’m getting hit with tear gas,” said Ace Michaud, 35.

Video shows man disarming person with stolen Seattle police rifle
Dramatic video showed an armed man disarming an apparent protester who had a stolen Seattle police rifle taken after police vehicles were burned Saturday.
Two rifles were stolen from Seattle police patrol cars that were burned amid the chaos, and both were recovered by a security guard working with a Q13 Fox News reporter, police said in a tweet.
The video from KOMO shows a man with what appeared to be a handgun taking the rifle from a bandanna-masked man, and then releasing the magazine. A Seattle police spokeswoman confirmed that rifle was one of the two stolen from the SPD vehicles, but did not confirm who disarmed the man.
The reporter, Brandi Kruse, tweeted that "our security guard felt that the public was in danger" and took the rifle from what she described as a rioter and disabled it.
Seattle police tweeted their thanks to the man for "safely recovering both rifles and potentially saving lives." One rifle had been fired but police said there were no reports of injury and they were unsure who fired it. Kruse tweeted that a person took the rifle and fired into vehicles, but no one appeared hurt.
Police said no arrests had been made.
