WATCH: Biden to use Boulder mass shooting to tighten gun control laws

As details about the suspect in the mass shooting at a King Soopers grocery store in Boulder, Colo. emerge, President Joe Biden and other high-ranking Democrats used the opportunity to push gun control.

Biden gave a statement, saying that it was time for the Senate to push through "common sense" gun reform laws, and wants specific action taken on "assault weapons and high-capacity magazines."

"We can ban assault weapons and high-capacity magazines in this country once again. I got that done when I was a senator. It passed, it was the law for the longest time and it brought down these mass killings. We should do it again."

Biden said that there was still not enough information on the shooter's motives or his identity, but that he "doesn't need to wait another hour" before taking action. He noted that closing "the Charleston loophole" would be one of the best tools "we have right now to prevent gun violence.

The Charleston loophole is the provision that, in the event a background check does not immediately return a yet or no verdict, a gun seller must wait three days for a further FBI check before allowing that customer to purchase a gun. If after three days the background check is still inconclusive, the seller is permitted to sell the firearm.

Biden said that he mourned the victims, that "ten lives have been lost and more families have been shattered by gun violence in the state of Colorado—Jill and I are devastated, and I just can't imagine how the families are feeling—the victims whose futures were stolen."

He assured Americans that "as president," he's going to "use all the resources at [his] disposal to keep the American people safe."

Biden has repeatedly said that the primary job of government is to keep Americans safe.

Former President Barack Obama jumped aboard the "gun control" bandwagon as well, releasing a statement that called for more action to prevent Americans from owning guns. Obama said that "It is long past time for those with he power to fight this epidemic of gun violence to do so."

He also said that "It will take time to roots out the disaffection, racism and misogyny that fuels so many of these senseless acts of violence. But we can make it harder for those with hate in their hearts to buy weapons of war."

New York's Senator Chuck Schumer called for "universal background checks" before a person could act on their right to own a firearm.

Rep. Cori Bush (D-MO) said that "We need gun control. Now."

According to Newsweek, "The AR-15 rifle cited by Boulder law enforcement officers to have been used in Monday's shooting hit the market in the early 1960s as the first civilian version of the military's M16 rifle."
