Multiple senior law enforcement officials briefed on the investigation into the attack at Speaker Nancy Pelosi’s house say it is too soon to say what a motive may have been for David DePape, the suspect.

Those officials say the focus of the investigation is to thoroughly review online posts which may or may not be attributable to DePape and to see if there are any social media accounts that also belong to him. They also say they expect both the FBI and San Francisco Police Department to take the next few days to speak with any of his associates or family members to try to derive a potential motive after, as NBC News has previously reported, the attacker specifically referenced Nancy Pelosi during the incident.

Two law enforcement officials say an early dive into his background and public-facing social media and blogs show a “mixed ideology” taking aspects of liberal anti-establishment ideas sometimes shared in the Bay Area to more recent posts that espouse ideas typically associated with far-right extremism.

Two law enforcement officials say there were cameras at the Pelosi home but the officials were not briefed on what those cameras specifically reveal or don’t reveal about the incident.

Rep. Ro Khanna, D-Calif., decried the attack on Paul Pelosi, and said the current political atmosphere is dangerous for public servants and their families.

Khanna, a member of the House Oversight and Reform Committee and the deputy whip of the Progressive Caucus, told MSNBC's Katy Tur that “it’s just so appalling that we’ve come to this state in our democracy, that Paul Pelosi can’t be safe in his own home.”

Asked if he feels safe, Khanna said, “I don’t think anyone in public life today is completely safe. I would say though, that there are other colleagues of mine, particularly women, women of color, who are bigger targets. And we have to really understand that words have consequences in political debate.”

“Everyone is at risk who is serving and it’s in everyone’s interest, not just the right thing to do, but in everyone’s interests, everyone’s family’s interests, to tamp down the rhetoric,” he added.

Khanna said there will likely be an assessment if there's a need for increased security for congressional leadership, but “beyond that, we all need to recognize the consequences of words that we utter on social media or in the public domain and what we’re doing in the atmosphere we’re creating in this country.”

Virginia Gov. Glenn Youngkin, a Republican, brought up the attack on House Speaker Nancy Pelosi's husband during a campaign event.

Youngkin, speaking at a rally Friday for GOP congressional candidate Yesli Vega, said voters were fed up with Democratic leaders and then briefly mentioned the violent assault.

"Speaker Pelosi's husband — they had a break-in last night in their house, and he was assaulted. There's no reason for violence anywhere, but we're going to send her back to be with him in California," Youngkin said, according to a reporter for The Associated Press, as well as a video clip posted on social media.

Rep. Donald McEachin, D-Va., criticized the remark on Twitter.

"This is a disgusting, vile, and crass comment by Governor Youngkin," he tweeted, adding, "This reprehensible behavior is beneath the dignity of his office."

Asked to clarify what Youngkin meant by his comments, spokesperson Kristin Davison told NBC News: “As the governor clearly said, the assault on Paul Pelosi was wrong and there is no place for violence. He wishes him a full recovery and is keeping the Pelosi family in his prayers.”

In a separate incident in August, Rep. Eric Swalwell, D-Calif., said a man called his office, repeating homophobic slurs and threatening to shoot and kill the congressman.

Swalwell, who has previously tweeted about threats to his office, wrote: “Bloodshed is coming.”

The man, Joshua Hall, pleaded guilty Friday to making threats to kill a member of Congress. In court testimony, Hall said he was drunk when he made the threat. He had previously pleaded guilty to fraud for impersonating relatives of Donald Trump in a scheme to steal thousands of dollars from Trump supporters.

SAN FRANCISCO — Law enforcement had the area around the Pelosi home blocked off with yellow tape Friday morning and at least a dozen police vehicles.

Agents wearing FBI jackets and local police uniforms crisscrossed the broad street in front of the home, which sits near the top of a hill in the wealthy Pacific Heights neighborhood.

Traffic was slightly disrupted as people in Tesla, Mercedes-Benz, BMW and Toyota Prius vehicles crept past the police tape to get a look, and a helicopter circled overhead.

Police identified the man who assaulted Paul Pelosi as David DePape, 42.

He's being hit with numerous charges, including attempted homicide and elder abuse. The motive is "still being determined," San Francisco Police Chief William Scott told reporters in a brief news conference.

Scott said Paul Pelosi and the suspect were both holding a hammer when police arrived at the home shortly before 2:30 a.m. PT. "The suspect pulled the hammer away from Pelosi and violently assaulted him with it" before officers tackled him, Scott said.

The violent assault on House Speaker Nancy Pelosi's husband could draw greater attention to security threats on Capitol Hill.

Paul Pelosi was attacked at their home in California, authorities said. But according to statistics from the U.S. Capitol Police in June, security threats are rising against members of Congress.

The USCP Threat Assessment Team saw a 144% increase in new cases between 2017 to 2021 — from 3,939 in 2017 to 9,625 in 2021. The first three months of this year saw roughly 1,820 cases opened by that team.
