Pennsylvania's senators are commenting on the hours long Philadelphia standoff during which six city police officers were shot.
U.S. Sens. Pat Toomey and Bob Casey both said lawmakers should strengthen gun safety laws.
Casey thanked city law enforcement for responding to the scene and keeping residents safe.
He called for new gun violence legislation:
Gun violence is a public health epidemic and it's long past time for Congress to take action to address it. There are commonsense steps we can take to reduce the likelihood that a person can threaten a community with a military-style assault weapon and we must take them. Majority Leader McConnell should call the Senate back to Washington immediately to debate and vote on gun violence legislation.
Toomey commented on the shootings:
The shooter who attempted to murder brave Philadelphia police officers yesterday is a convicted felon who had no right to possess a firearm. In the coming weeks, more information will hopefully come to light on how the suspect obtained his weapons, and I have asked ATF and the Department of Justice to keep me apprised of any new information. We can do more to strengthen our gun safety laws and better protect law enforcement. When Congress reconvenes, these issues, such as strengthening background checks to keep guns out of the hands of violent criminals, should be a top priority.
