Satcher said Walensky was brave for speaking out.

“This might mean — could well mean — taking some risks, so I salute Dr. Walensky,” Satcher said.

The CDC’s plan

In April, President Joe Biden said the country was facing “a gun violence public health epidemic,” but the CDC hasn’t said how it plans to address the epidemic until now.

“I swore to the President and to this country that I would protect your health. This is clearly one of those moments, one of those issues that is harming America’s health,” Walensky said.

Decades after lobbying pressure and politics all but stopped gun violence research, Walensky’s plan is to restart that research and identify effective solutions.

“We don’t even know who enters the emergency department, in most places, as a result of firearm injury — we don’t even know it,” Walesnky said.

“My job is to understand and evaluate the problem, to understand the scope of the problem, to understand why this happens and what are the things that can make it better – to research that, to scale that up, to evaluate it and to make sure that we can integrate it into communities,” Walensky said. “We have a lot of work to do in every single one of those areas because we haven’t done a lot of work as a nation in almost any of them.”

The CDC once did these kinds of studies — until 1997, when the NRA convinced Congress to cut all of the CDC’s funding for gun research, a loss equivalent to millions of dollars a year.

Walensky said much of CDC’s research will be engaged in understanding the root causes of gun violence.

“Oftentimes these will be escalating events that occur that might lead to a suicide or a homicide, and what we really need to do is understand the root causes of that,” she said. “The firearm injury is probably the most distal part of what happens. It is the end event. What are the 10, 12, 15 things where we could have intervened before that singular event?”

A colleague’s tragedy

Walensky is an infectious diseases specialist, but in 2012, she witnessed firsthand the grief caused by gun violence.

At the time, she was a professor at Massachusetts General Hospital, where Dr. Chana Sacks was a resident. Sacks awoke on December 14 to learn that her cousin’s son, Daniel Barden, had been shot at the Sandy Hook Elementary School in Connecticut. Daniel, a first grader, died that day.

Determined to find a way to curb gun violence, Sacks turned to Walensky, one of her closest mentors.

While mentors often direct young doctors to do research in well-funded specialties, Sacks says Walensky encouraged her to go into gun research, which was — and still is — politically charged and not very well funded.

“It was one step at a time, and Rochelle really helped me figure out each step, how I could find pathways to make this work,” Sacks told CNN.

“This is inherently emotional work and Rochelle has helped me through a lot of tears,” Sacks said. “She saw that pain up close and there is no way to not be affected by it.”

‘I’m not here about gun control’

In restarting gun violence research, Walensky said she wants the CDC to find common ground with gun owners.

“Let’s agree, we don’t want people to die. Let’s just agree there. What can we do to stop people from dying, and what can we do to stop people from being injured,” she said.

Walensky seems careful to avoid the ire of gun rights activists — she doesn’t even like using the word “gun,” preferring the term “firearm.”

“Generally, the word gun, for those who are worried about research in this area, is followed by the word control, and that’s not what I want to do here,” she added. “I’m not here about gun control. I’m here about preventing gun violence and gun death.”

She said she doesn’t want people to think she is trying to take away their guns.

“This is not a conversation about having them or not having them. This is a conversation about how we can make them being here safe,” she said. “The research that we intend to do is going to be squarely about making America safe. Making people safe.”

She invited gun owners to be part of the solution.

“Come to the table. Join us in the conversation,” she said. “I want you to teach me what you have done to make your gun safe, and then I want you to teach everybody else,” she added.

“We cannot understand the research of firearm violence, firearm injury, without embracing wholeheartedly, the firearm owning community,” she added. “I really do believe that the population of people who wants to own a gun doesn’t want people hurt by them. The majority of the population does not want people hurt by them. I want them at the table.”

CNN reached out to the NRA to ask if it was willing to work with Walensky. A spokesperson for the NRA did not respond to CNN’s request for comment.

When gun owners hear that the CDC wants to reduce gun violence, they’ll think that the government wants to take away their guns, said Dr. Chris Barsotti, an emergency physician and gun owner who teaches children in the firearm education program in Vermont.

“They’re going to think this is another political approach to make it difficult to access guns or potentially confiscate guns or create barriers to access,” Barsotti said.

Barsotti and other gun owners say there are committed to reducing gun violence. He is the founding CEO of the American Foundation for Firearm Injury Reduction in Medicine.

The NRA’s next steps

By speaking up, Walenksy risks enraging the NRA.

If the gun lobby again pressures Congress to cut CDC gun research funding, it’s unclear if lawmakers will acquiesce as they did in 1997.

“Is the NRA down and out enough that they can’t muster an all-out assault on the CDC? Or is that totally crazy thinking because the NRA can always muster any assault at any time?” said McGuire, executive director of the Trauma Foundation, an injury prevention organization.

Even if the NRA does mount an all-out war against the CDC, it’s not clear that Republican members of Congress will respond as obediently as they did 25 years ago, McGuire added.

“Are members of Congress who have been in their grip thinking of the NRA as a wounded animal and so maybe aren’t in their grip anymore?” he said.

While Walensky said she worries that just saying the word guns or talking about firearms could anger many Americans, she said she’s committing to pursing the gun violence research.

“I also worry that if we don’t do anything about it, we have a whole sector of the United States that gets really angry,” she said. “This is one of the leading killers of our young people in this country. It’s a high priority.”

Sacks, her former colleague in Boston, said Walensky is a determined person.

“If you’ve spoken to Rochelle for ten minutes, you know that when she focuses on something with intensity, it’s going to happen,” she said.
