The House Judiciary Committee heard from a panel of experts and victims of gun violence Wednesday.
Democrats are proposing a bill to require universal background checks for gun purchases.
In 2017, 40,000 Americans were killed by guns, according to data from the Centers for Disease Control.
Chairman of the House Judiciary Committee Jerry Nadler said no other developed country has such high gun violence rates.
Lawmakers heard from victims of gun violence, including a survivor of the Marjorie Stoneman Douglas shooting, who hid under her classmate’s body.
“I matched his every movement and hid underneath his lifeless body as bullets riddled my classmates,” said Aalayah Eastmond, mass shooting survivor.
Some witnesses asked for stronger gun laws to keep Americans safe, but gun rights advocates said they need to be able to protect themselves.
Democrats introduced a companion bill in the U.S. Senate.
