President Biden encouraged lawmakers Tuesday to get a bill banning assault weapons to his desk and take immediate action following the mass shooting in Half Moon Bay, California, despite few specifics on what type of gun was used.

Authorities have indicated the gunman used a semiautomatic rifle, but have not said if the rifle is a so-called "assault" weapon.

At least seven people were shot dead and an eighth victim injured Monday afternoon at two separate locations in the northern California coastal city just south of San Francisco. 

"Yesterday, Senator Feinstein — alongside Senators Murphy, Blumenthal and others — reintroduced a federal Assault Weapons Ban and legislation that would raise the minimum purchase age for assault weapons to 21," Biden said in a statement Tuesday morning. "Even as we await further details on these shootings, we know the scourge of gun violence across America requires stronger action."
