Furious neighbors want JD Vance to move out. What did he do?

After the assassination attempt on Donald Trump in Pennsylvania, Secret Service has tightened the security of Trump's running mate JD Vance resulting in a closure of a park at the area where JD stays with his family in Alexandria. Neighbors are at a loss to understand why the park was a security threat for the Ohio senator and that he should move out if he has a security threat in the area itself.
