Good evening. I want to start with a video clip that says far too much about being a kid today.

These are young children, single file holding hands. They're being taken not on a field trip to see the dinosaurs,

but out of harm's way from the scene of a school mass shooting. Another one, this time in Nashville,

at the Covenant School, a private Christian school for kids from pre-K age to sixth grade.

Reading from its webpage, The Beauty of a Pre-School, sixth school is in its simplicity and innocence.

Students are free to be children. The website says, Celebrating Childhood says at the top of the homepage.

Two girls and a boy, reportedly all-none, were murdered there today by a 28-year-old former student who also murdered three adults before being killed by police.

The children were at Evelyn Dickhouse, William Kinney, Halleys Scruggs, and Halle's dad is senior pastor of Covenant Presbyterian Church,

which runs the school, two of the adults murdered Cynthia Peake and Mike Hill were both 61.

Mike Hill's friend posted this photo of him online, said Mr. Hill was the last employee hired when he ran the school in church kitchen,

said he was the kind of person who would sacrifice for others.

Catherine Coons was also murdered. She was 60, head of the Covenant School, her daughter is also a teacher there.

Police say her killer, who they say was transgender, was carrying a handgun into assault-style rifles.

President Biden today called on Congress to do what it showed no willingness to do since the federal ban on such weapons expired in 2004.

So I call on Congress again to pass my assault weapons ban.

It's about time that we began to make some more progress, but there's more to learn.

But I just wanted to send my concern and hearts out to so many parents out there.

As for lawmakers, Texas Republican Senator John Cornyn, who helped pass a more limited gun safety package during the last Congress,

says he doesn't believe any more legislation will move on the issue in the next two years.

Senator Cornyn telling CNN's monorogia that an assault weapons ban would affect, quote, law-abiding citizens.

But later we'll be joined by his Democratic counterpart from Connecticut Senator Chris Murphy.

Right now, I want to go to Nashville and CNN's Carlos Suarez. So what do we know now about how the attack unfolded Carlos?
