In the wake of thesecond-deadliest school shootingin United States history — one ofhundredsthe country has seen in recent months — PresidentJoe Bidenon Thursday offered an urgent plea to Americans: “How much more carnage are we willing to accept?”

In a primetime address to the nation Thursday night — delivered while many Republicans across the countrycontinue to call for increased school security, rather than increased gun regulations— Biden, 79, called on Congress to reinstate a nationwide assault weapons ban and institute a number of other gun reform measures.

Easy access to high-powered guns, the president said, are to blame for the influx in mass shootings and the countless deaths of people at shopping malls, supermarkets, churches and in elementary schools.

“This time,” Biden said, “we must actually do something.”

Speaking about his recent trip with first ladyJill Bidento Uvalde, Texas — where a gunmankilled 19 elementary school students and two teacherslast month — Biden said the school was like countless other “everyday places that have become killing fields, battlefields here in America.”

The survivors and family members of victims of gun violence, Biden said, had one request: “Do something. Just do something. For God’s sake, do something.”

“After Columbine, after Sandy Hook, after Charleston, after Orlando, after Las Vegas, after Parkland, nothing has been done,” he continued. “This time, that can’t be true. This time, we must actually do something.”

Noting that he respects “the culture and the tradition and the concerns of lawful gun owners,” the president made clear that he doesn’t intend to vilify gun owners, nor take away anyone’s guns.

But the Second Amendment, he said, “is not absolute.”

“We need to ban assault weapons and high-capacity magazines,” Biden said Thursday. “And if we can’t ban assault weapons, then we should raise the age to purchase them from 18 to 21.”

“But after Republicans let the law expire in 2004 and those weapons were allowed to be sold again, mass shootings tripled,” he added. “Those are the facts.”

Biden added a litany of other gun reform measures he would like to see, including stronger background checks, safe storage laws and red-flag laws, a repeal of “the immunity that protects gun manufacturers from liability,” and a limit to how many rounds of ammunition a weapon can hold at once.

Biden also proposed addressing “the mental health crisis deepening the trauma of gun violence and as a consequence of that violence.““These are rational, commonsense measures,” Biden continued, adding a poignant message regarding a Uvalde shooting survivor.

“Imagine being that little girl — that brave little girl in Uvalde who smeared the blood off her murdered friend’s body onto her own face to lie still among the corpses in her classroom and pretend she was dead in order to stay alive,” he said. “Imagine — imagine what it would it be like for her to walk down the hallway of any school again.”

As Biden noted in closing his remarks, the House of Representatives has already passed some of the key measures he proposed — though many havestalled in Congress.

Now, he said, it’s up to the Senate, which is evenly split among Republicans and Democrats — making gun reform an uphill battle.

“For the children we’ve lost, for the children we can save, for the nation we love, let’s hear the call and the cry,” Biden said, in closing. “Let’s meet the moment. Let us finally do something.”
