A fierce advocate for stricter gun laws and restrictions on semiautomatic weapons, Feinstein responded to the Las Vegas shooting - the deadliest mass shooting in recent US history - by calling for a ban on bump stocks, devices that allow some semiautomatic weapons to mimic an automatic weapon, which are illegal. The devices, which were used in the attack that killed 58 people at an outdoor concert in Las Vegas on October 1, enable some rifles to be used like automatic weapons.
The White House also said the idea should be examined. Feinstein has introduced Senate legislation to ban the sale or use of the devices. She lamented the stratified lines of debate in "a gun-happy country".
Feinstein has bucked the left wing of her party on occasion, including during the state's recent push to enact single-payer health care, and she is nearly certain to face a primary challenge.
The National Rifle Association last week expressed openness to banning bump stocks. Technically, that means the finger is pulling the trigger for each round fired, keeping the weapon a legal semi-automatic.

Seeking broader consensus, Sen. A spokesman for Feinstein confirmed its veracity to CNN.
