(CNN)President Joe Biden on Wednesday urged Congress to “take immediate action” on gun legislation in the wake of a shooting in San Jose, California, that killed eight people earlier in the day, noting that he was ordering the flag lowered to half-staff just weeks after other mass shootings around the country.“Enough,” Biden said in a statement. “Once again, I urge Congress to take immediate action and heed the call of the American people, including the vast majority of gun owners, to help end this epidemic of gun violence in America.”A gunman killed eight people when he opened fire at public transit rail yard. The investigation is ongoing and officials have not released a possible motive. The shooter, an employee of the Valley Transportation Authority (VTA), is also dead.Biden described the shooting as a “horrific tragedy” and said he and Vice President Kamala Harris, who also called on Congress to act, had been briefed on the situation.“We are still awaiting many of the details of this latest mass shooting, but there are some things we know for sure. There are at least eight families who will never be whole again. There are children, parents, and spouses who are waiting to hear whether someone they love is ever going to come home. There are union brothers and sisters — good, honest, hardworking people — who are mourning their own,” Biden said.The President added: “Every life that is taken by a bullet pierces the soul of our nation. We can, and we must, do more.”Biden’s ordering of the flag to be lowered follows recent mass shootings in and around Atlanta, Indianapolis, Boulder, Colorado, and Rock Hill, South Carolina.
