JEFFERSON CITY (AP) – A Missouri House panel endorsed legislation that would send federal agents to jail for enforcing some federal gun control laws.

The House General Laws Committee advanced the measure Thursday. It passed the Missouri Senate last month.

The bill would declare federal laws that the state considers infringements on gun rights to be null and void. Federal agents enforcing those laws could face civil penalties and be prosecuted for a new crime, punishable by up to one year in jail and a $1,000 fine.

Courts have consistently ruled that states cannot nullify federal laws.

The bill would also allow designated school personnel to carry concealed weapons in school buildings. It now heads to the House Rules Committee before moving to the floor.
