BOISE, Idaho (AP) — Hundreds swarmed the Statehouse steps waving signs in protest of a bill that would allow firearms on Idaho college campuses.

Students and professors spoke out against the bill at the Thursday rally, through a light drizzle.

Many said having allowing concealed carry permit holders to tote guns to classrooms and around campus would disrupt a learning environment and force schools to implement costly security measures.

The legislation passed the Senate 25-10 earlier this month.

Multiple police chiefs and heads of all eight universities have told the Legislature they don’t want to see firearms on campuses.

They said bringing those firearms onto a campus was a matter of Second Amendment rights, and would allow students and staff to protect themselves.
