A rally of white nationalists in Charlottesville, Virginia led to three deaths after a violent confrontation between demonstrators and counterprotesters on Saturday. A 32-year-old female counterprotester was killed when a car appeared to deliberately drive into crowds and then reversed and hit more people, while two Virginia state troopers, responding to the situation, died when their helicopter crashed outside the city.

Attorney General Jeff Sessions said the Department of Justice would be opening a civil rights investigation. “The violence and deaths in Charlottesville strike at the heart of American law and justice. When such actions arise from racial bigotry and hatred, they betray our core values and cannot be tolerated,” he said.

Fields, a 20-year-old resident of Ohio, was charged with murder, three counts of malicious wounding, and one count of hit-and-run attended failure to stop with injury. The NY Times notes, “the authorities declined to say publicly that Mr. Fields was the driver of the car that plowed into the crowd.”

The white nationalist rally, called “Unite the Right,” was organized by Jason Kessler, whose permit had initially been turned down. The ACLU came to his defense, and the rally was allowed to go on, after a judge found the permit was likely turned down because of the content of the rally, versus public safety factors, according to the Daily Progress.

But by 11:30 a.m. on Saturday, the rally was cancelled when, Kessler said, the Charlottesville Police “declared an unlawful assembly and forced us to leave.”

In the early afternoon, when counterprotesters were marching on a downtown street, a Dodge Charger suddenly slammed into the crowd near 4th Street and Water Street. Podcaster and University of Virginia student Robert Armengol told the NY Times, “It was probably the scariest thing I’ve ever seen in my life. After that it was pandemonium. The car hit reverse and sped and everybody who was up the street in my direction started running.”

Virginia Governor Terry McAuliffe also called a state of emergency.

In an afternoon press conference, President Donald Trump said, “We condemn in the strongest possible terms this egregious display of hatred, bigotry and violence on many sides — on many sides. It’s been going on for a long time in our country. Not Donald Trump, not Barack Obama. It’s been going on for a long, long time. It has no place in America. What is vital now is a swift restoration of law and order and the protection of innocent lives. No citizen should ever fear for their safety and security in our society, and no child should ever be afraid to go outside and play or be with their parents and have a good time.”

However, Trump was criticized for not specifically denouncing the white nationalist views, which other politicians—including prominent Republicans—did:

This morning, the president’s daughter, Ivanka Trump, specifically said, “There should be no place in society for racism, white supremacy and neo-nazis. We must all come together as Americans — and be one country UNITED. #Charlottesville”

Bloomberg News reporter Margaret Talev says that a White House spokesperson told her on Sunday morning, “The President said very strongly in his statement yesterday that he condemns all forms of violence, bigotry and hatred and of course that includes white Supremacists, KKK, neo-nazi and all extremist groups. He called for national unity and bringing all Americans together.”
