In a first-of-its-kind survey, NBC News polled Gen Z voters ahead of the 2024 election and the results were surprising. The poll explored voter sentiments and issues surrounding the election. NBC News’ Savannah Sellers spoke with some young voters about the 2024 election and their views on the Harris campaign.

During remarks in Portsmouth, New Hampshire, Harris addressed the school shooting in Georgia, telling attendees, "Our hearts are with the students, the teachers and their families, of course."

She called the incident a "senseless tragedy on top of so many senseless tragedies" and called it "outrageous" that "everyday in our country ... parents have to send their children to school worried about whether or not their child will come home alive."

The vice president also said that "we have to end this epidemic of gun violence in this country once and for all ... it doesn't have to be this way."

Following the announcement of new sanctions targeting what the Biden administration describes as Russian government-sponsored attempts to manipulate U.S. public opinion, White House National Security spokesman John Kirby told reporters that "RT is no longer just a propaganda arm of the Kremlin; it’s being used to advance covert Russian influence actions."

Kirby said that the RT network was being used "to funnel disinformation through outlets and social media influencers that a certain number of Americans find credible. We will not stand for that."

He added that the U.S. government believes Russian officials, as high as Russian President Vladimir Putin, were weighing in on RT's operation.

President Joe Biden criticized Republicans’ stance on gun control and said that the White House was closely working with state, local and national law enforcement after a mass shooting at a high school in Georgia.

“After decades of inaction, Republicans in Congress must finally say ‘enough is enough’ and work with Democrats to pass common-sense gun safety legislation," the president said in a statement. "We must ban assault weapons and high-capacity magazines once again, require safe storage of firearms, enact universal background checks, and end immunity for gun manufacturers.”

House Speaker Mike Johnson, R-La., praised law enforcement for their response in today's Georgia high school shooting.

"Our prayers go out today for the Apalachee High School community, and especially the victims and their families who have endured this terrible tragedy," he wrote in a post on X. "The officers of the Winder Police Department are commended for their quick action in apprehending the suspect. May justice here be swift."

During a campaign stop in Lancaster, Pennsylvania, Walz addressed the high school shooting in Georgia.

"We don’t know any of the details on it yet, but it’s a situation that’s all too common, and our hearts are out there right now," he said, adding that "work" should be focused on how to "prevent these in the future."

Ahead of his news conference on election threats, Attorney General Merrick Garland addressed the shooting at a high school in Winder, Georgia. He said the FBI and ATF are on scene to assist local law enforcement.

"I'm devastated for the families who have been affected by this terrible tragedy," he said. "The Justice Department stands ready to provide any resources or support that the Winder community needs."

Rep. Lucy McBath, D-Ga., who lost her son Jordan Davis to gun violence in 2012, said in a post on X: "I am praying for the students of Apalachee High School and the community of Winder. I am praying for families across our state and entire country. Too many continue to experience the pain of gun violence. No family should have to go through this."

McBath became active in efforts to curb gun violence after her son's killing and made the issue a main thrust of her campaign for Congress in 2018.

Gov. Brian Kemp said in a statement on X that he has ordered the state to aid in the response to the shooting at a high school in Winder, Georgia.

"I have directed all available state resources to respond to the incident at Apalachee High School and urge all Georgians to join my family in praying for the safety of those in our classrooms, both in Barrow County and across the state," he wrote.

Biden has also been briefed by his homeland security adviser, Liz Sherwood-Randall, as his administration coordinates with state and local partners, a White House official said.
