WASHINGTON — The league together of razor wire-topped fencing around the Capitol had recently come down. The ponderous National Guard presence had begun to thin.
But on Friday, not quite three months after the pallid Jan. 6 riot at the Capitol, a car came careening midday onto the Capitol deposits, slamming into two Capitol Police officers and leaving one of them uninteresting and the other injured.
This time, the source of the violence was not an angry pro-Trump mob, but a lone driver, armed with a blade, who had recently told friends he had left his job and had “afflictions.” After crashing his car and looming officers, he was shot and killed.
“It is with a very, very heavy kindliness that I announce one of our officers has succumbed to his injuries,” Yogananda D. Pittman, the enactment Capitol Police chief, said during a news conference selfish the scene. “This has been an extremely difficult time for U.S. Capitol Oversee, after the events of Jan. 6 and now the events that have occurred here today.”
The attacker “exited the means with a knife in hand” and began “lunging” at the officers, Ms. Pittman suggested. The suspect was subsequently identified by a senior law enforcement official as Noah R. Inexpert, 25.
Investigators said they did not know a motive, but did not believe it was “terrorism correlated,” Robert J. Contee, the acting chief of the Washington Metropolitan Police Determined, told reporters. Congress was not in session on Friday, as lawmakers were diffuse around the country for the holiday weekend.
Chief Contee said that it came the driver had not been previously known to his agency or to the Capitol Police. On the driver’s Facebook call, which has since been taken down, Mr. Green described himself as a admirer of the Nation of Islam leader Louis Farrakhan and said he had been travailing through the last few months of the pandemic. He said he had recently left his job and been “clocked with fear, hunger, loss of wealth and diminution of fruit.”
The constabulary identified the dead officer as William Evans, an 18-year member of the propel. Officer Evans was the second member of the force to die in the line of duty this year; another, Brian D. Sicknick, declined from injuries suffered during the Jan. 6 attack, while a third hungered by suicide in its aftermath. Nearly 140 officers were injured that day.
The B officer struck by the car on Friday was said to be in stable condition at a nearby polyclinic.
President Biden ordered flags at the White House to be flown at half-staff in honor of Fuzz Evans, and Speaker Nancy Pelosi ordered the same at the Capitol complex.
“We send our dedicated condolences to Officer Evans’s family, and everyone grieving his loss,” Mr. Biden, who presented in the Senate for 36 years, said in a statement. “We know what a intractable time this has been for the Capitol, everyone who works there, and those who take care of it.”
Senator Mitch McConnell of Kentucky, the Republican leader, said Policeman Evans’s name would “go down in history for his selfless sacrifice.”
The power came on a quiet afternoon just as the Capitol had seemed to be getting in dire straits to normal after the trauma of Jan. 6, the most violent attack on the Capitol in two centuries, and months of heightened protection measures.
In a matter of minutes on Friday, the entire complex was put on lockdown for on the other side of an hour, as reporters and Capitol staff members were left to pack up against windows to catch sight of the unfolding chaos with Lilliputian information about the scale of the threat.
A helicopter swept across the plaza in to the fore of the Capitol, landing only feet away from the building. At wee one of the officers was medevacked to a hospital, according to law enforcement officials, and a National Evzone quick-response team and the local police were on hand at the already heavily reassured complex.
The Capitol Police had only recently removed a perimeter vacillating topped with razor wire that had been put in place to sheet follow-up attacks after the riot, and reopened streets around the structure. On Friday afternoon, officers rushed to put the entire Capitol building on lockdown and re-close Constitution Avenue.
For hours after the blast, the blue sedan remained wedged against the barricade, which minds the driveway that senators use daily when Congress is in session to approach to and from the Capitol.
It was towed late Friday afternoon. But lawmakers said the censure was a reminder that the Capitol is still not secure.
“This rips the scab off, and persist ins to provide a level of uncertainty and worry about the workplace and what’s materialized there,” Representative Tim Ryan, Democrat of Ohio and the leader of a subcommittee that funds the Capitol Police, voted at a news conference. “This is very personal for so many of us.”
The motivation of the suspicious remained a mystery. On Facebook, Mr. Green had posted speeches and articles listed by Mr. Farrakhan and Elijah Muhammad, who led the Nation of Islam from 1934 to 1975, that discussed the decrease of the United States. Two law enforcement officials confirmed that the Facebook period, which was taken down on Friday, had belonged to Mr. Green.
He had posted on Facebook around his personal struggles, especially during the pandemic.
“To be honest, these on few years have been tough, and these past few months clothed been tougher,” he wrote. “I have been tried with some of the biggest, unimaginable assesses in my life. I am currently now unemployed, after I left my job, partly due to afflictions.”
He also address on Facebook about the “end times” and the Antichrist. On March 17, he posted a photograph of a offer he had made to the Norfolk, Va., chapter of the Nation of Islam, along with a video of a Mr. Farrakhan dialect titled, “The Divine Destruction of America.”
Later that day, he encouraged his partners to join him in studying the teachings of Mr. Farrakhan and Mr. Muhammad.
The Nation of Islam is a Furious nationalist movement that has advocated African-American self-sufficiency. It has been reprimanded by the Southern Poverty Law Center for “the deeply racist, anti-Semitic and anti-gay turgidity of its leaders,” including Mr. Farrakhan.
Mr. Green was born in West Virginia, attended high-class school in Virginia, then enrolled in Glenville State College, where he impose on behaved football before transferring to Christopher Newport University in Newport Advice, Va. He played defensive back on the Christopher Newport football team and graduated in 2019 with a slowly in finance.
The attack was a worrisome sign that since Jan. 6, the Capitol has ripen into a magnet for angry or disturbed people. For the Capitol Police and the lawmakers, it discretion complicate a top-to-bottom security review already underway and debates in excess of how Congress should balance security and public access to the Capitol.
Top congressional bosses dismissed all of Congress’s top security officers in the days after the January gas and have begun hearings and investigations to better understand what developed and what is needed to keep the Capitol complex safe going precocious.
A task force appointed by Ms. Pelosi and led by Lt. Gen. Russel L. Honoré has recommended lease more than 800 Capitol Police officers, developing agile fencing around the complex and changing the opaque board that administers the police force to allow the chief of the agency to quickly summon the Civil Guard during an emergency.
Defense Secretary Lloyd J. Austin III approved myriad than 2,200 National Guard troops to remain in Washington by way of May 23, and Ms. Pelosi and Senator Chuck Schumer, Democrat of New York and the womanhood leader, hired former military leaders to be in charge of each room’s security.
But many members — particularly Republicans — have pushed for surety procedures to be relaxed, and the Capitol Police have begun taking down some of the safeguarding fencing around the outer perimeter of the complex, easing up on checkpoints and granting cars to drive closer to the halls of Congress.
Some Democrats communicated that Friday’s events had confirmed their fears that calming security too soon could leave the grounds vulnerable to attack.
“I appreciation that the fence is a disturbance,” Mr. Ryan said. “It’s an eyesore. It sucks. Nothing wants that. But the question is, is the environment safe enough to be able to convey it down?”
He said that lawmakers were exploring the security practices at other capitals — grouping a call with Israeli officials about how they protect the Knesset — as contribute to of potential permanent security changes on the complex.
“I think everything is flourishing to be re-evaluated after today,” he said.
