Washington gov signs big gun control package, including 'assault weapons' ban: 'No one needs an AR-15'

The mood at the Washington State Capitol was jubilant Tuesday as Gov. Jay Inslee signed a trio of gun control bills, one of which immediately bans the manufacture, purchase or importation of so-called assault weapons.

"Party safely tonight," the governor told supporters after signing the bills.

Inslee and Attorney General Bob Ferguson, both Democrats, pushed for the gun control package.

With the governor's signature, Washington becomes the 10th state to adopt an "assault weapons" ban.

"No one needs an AR-15 to protect your family," Inslee said while surrounded by family members of shooting victims. "You only need it to kill other families."
