Kansas Gov. Sam Brownback says he’s not second-guessing a new state law that would require the state’s college campuses to allow concealed weapons.

The Republican says the law is in accordance with the Constitution’s Second Amendment’s right to bear arms.

In 2013, Kansas lawmakers passed and Brownback signed a bill mandating that concealed weapons be allowed in nearly all public buildings unless adequate security is in place to prevent anyone from bringing in a weapon.

Public colleges and universities were given until 2017 to come into compliance with that law.

The University of Kansas’ chancellor and 70 of that school’s distinguished professors publicly have spoken out against the law.
