Some lawmakers across the country are scaling back events and appearances following the assassination of conservative activist Charlie Kirk.

"The events that unfolded on Wednesday are beyond tragic," Haddon Heights Mayor Zach Houck said.

Two days after Kirk was shot and killed at a Utah Valley University event in front of thousands of people, Camden County leaders announced a town hall scheduled for Friday night in Haddon Heights had been canceled due to what they called a "heightened political climate and increased security concerns."

"The safety of all the attendees, especially the Haddon Heights residents and the participants, is first and foremost on our minds at all times," Houck said.

Houck was set to speak at the Camden County Town Hall inside Haddon Heights High School alongside Democratic U.S. Rep. Donald Norcross, Camden County commissioners and New Jersey Assemblyman William Spearman.

Houck says around 500 people were expected at the event, which was an opportunity for them to ask questions about things happening in their towns.

"We just feel it best to hit pause and take a second to just reassess how we host our town halls," Houck said.

Norcross released a statement to CBS News Philadelphia that reads, in part, "We are all working with our law enforcement agencies to reevaluate how we structure our public events to keep people safe. Speaking with constituents at town halls is one of my favorite parts of the job and that is why I have held 111 town halls during my time in Congress. I look forward to rescheduling in Haddon Heights soon."

Lawmakers elsewhere have canceled events following the deadly shooting in Utah, including California Gov. Gavin Newsom and U.S. Rep. Alexandria Ocasio-Cortez (D-NY).

"The whole thing is sad that everybody has to cancel anything they're involved with because everybody is worried for their safety," Haddon Township resident Kathy Shone said.

"It's a great tragedy, and the fact that politicians are running for cover and they have to have even more security, it's a sad state of affairs for our country," Haddon Township resident Ken Koch said.

Officials in Camden County made it clear there was no known threat, but the town hall was canceled out of an abundance of caution.

County leaders say they will continue to host town halls in the future, but they want to make sure the right security is in place. A new date has not been announced.
