A US Capitol police officer was killed and a second injured Friday after a vehicle rammed through security and crashed into a barrier at the Washington complex, forcing it into lockdown less than three months after a mob assault on Congress.
Capitol Police shot dead the driver after he jumped out of the car and lunged at them with a knife, Acting Chief Yogananda Pittman told reporters.
President Joe Biden, who was with first lady Jill Biden at Camp David for the Easter holiday, offered his “heartfelt condolences” to the family of William Evans, the veteran policeman killed in the attack.
“Jill and I were heartbroken to learn of the violent attack at a security checkpoint on the US Capitol grounds,” Biden said in a statement.
US media said officials had identified the attacker as Noah Green, a 25-year-old black man from Indiana and an adherent of the Black nationalist Nation of Islam movement.
Pittman said there was no immediate indication of his motivation or police file on him.
“It does not appear to be terrorism-related, but obviously we will continue to investigate,” Washington Metropolitan Police Chief Robert Contee added.
Green had graduated from Christopher Newport University in Virginia, where he played football, with a degree in finance in 2019, the school confirmed.
Some of his online postings in March suggested a level of despair and paranoia. He said he was unemployed and had health problems, and made references to biblical concepts of the end of times.
He wrote that he had faced “unimaginable tests” and was “in search of a spiritual journey.”
In one post he spoke of being tormented by the FBI and CIA, hospitalised and subjected to “mind control,” and called the government “the #1 enemy of Black people!”
He also said he was a follower of Louis Farrakhan, the leader of the Nation of Islam, who promotes Black nationalist, anti-white and anti-Semitic thinking.
Facebook said it had removed Green’s account from the social network as well as Instagram, and that it would remove “any content that praises, supports, or represents the attack or the suspect.”
‘Martyr for democracy’
Top officials expressed shock over the attack and sympathy for Evans, an 18-year veteran of the force.
House Speaker Nancy Pelosi ordered flags lowered to half-staff on the Capitol, calling Evans “a martyr for our democracy.”
“Members of Congress, staff and Capitol workers, and indeed all Americans, are united in appreciation for the courage of the US Capitol Police,” she said.
Biden also lowered White House flags.
“We know what a difficult time this has been for the Capitol, everyone who works there, and those who protect it,” he said.
The attack came with scars still raw and security tight after the January assault on Congress by hundreds of supporters of then-President Donald Trump.
National Guard troops were mobilized Friday and staff at the huge Capitol complex ordered to stay away from windows and seek cover after alerts went out over the incident shortly after 1:00 pm (1700 GMT).
While Congress was in recess for the Easter holiday, text messages sent to staffers still working inside told them no one could enter or leave the building.
“If you are outside, seek cover,” the messages said, while television footage showed what appeared to be the attacked officers being loaded onto gurneys and into ambulances.
A blue sedan could be seen crashed into a security barrier on one of the streets leading to Congress.
Memory of 6 January
In the 6 January attack, hundreds of extremist Trump-backers smashed into the Capitol building yelling threats against politicians and shutting down the legislature.
One Capitol Police officer died as a result of the attack, as well as four other individuals who took part or were nearby.
Since then security officials have said there is an ongoing threat from extreme-right groups and Trump supporters.
More than 300 people have been charged in the January attack, including members of armed extremist groups like the Proud Boys and Oath Keepers, and 100 more are expected to be charged, according to Justice Department court filings.
In recent weeks some security around the complex has been loosened, with the number of armed National Guard troops at the Capitol reduced and a security fence that created a broad perimeter around the Capitol complex removed.
But permanent barriers remain in place on all the roadway entrances to the Capitol, well-manned by police and national guard.
“I drive through this checkpoint and wave to the officers guarding it nearly every day that I’m in Washington. I’m heartbroken to learn of an officer’s death in today’s attack,” tweeted Representative Angie Craig.
Security officials, including the Capitol Police and National Guard, were faulted for reacting slowly to the crowds who stormed the Capitol on 6 January.
But, Pittman said, they also remain on edge. “This has been an extremely difficult time for the US Capitol police after the events of 6 January, and after the events that have occurred here today,” she said.
