Sen. Bob Casey plans to introduce a bill that would bar someone convicted of hate crimes from purchasing firearms, he announced Sunday in the wake of the deadly attack at a gay nightclub in Orlando, Florida.

The Pennsylvania Democrat plans to meet with lesbian, gay, bisexual, and transgender community leaders in Pittsburgh on Monday to discuss “steps the United States government must take immediately to address safety concerns across the country from commonsense gun laws to ongoing acts of hate,” according to a statement from Casey’s office.

Casey’s announcement comes after a gunman opened fire at the Pulse nightclub early Sunday morning, killing at least 50 and sending 53 others to the hospital. Law enforcement is investigating the incident as an act of terrorism, amid reports that the gunman had expressed support for the Islamic State.

Casey, a member of the Senate Foreign Relations Committee, said in a statement that the attack highlighted the need to protect Americans from terrorists and address gun violence. The Orlando attack is the deadliest mass shooting in U.S. history.
