President Obama told a group of governors Monday that more must be done to prevent gun violence, after a shooting in Kalamazoo, Michigan this weekend.

Six people were killed and three wounded Saturday night by Jason Brian Dalton, an Uber driver who allegedly went on a shooting spree that lasted nearly five hours. Mr. Obama told members of the National Governors Association, who had gathered at the White House for a meeting Monday, that he called the mayor, sheriff and police chief in the town to offer federal support for their investigation.

He praised the local officials and first responders for an "outstanding job" but said there were still families who were shattered by the violence.

"Earlier this year, I took some steps that will make it harder for dangerous people like this individual to buy a gun. But clearly, we're gonna need to do more if we're gonna keep innocent Americans safe," Mr. Obama said, referring to executive actions he took earlier this year to try to increase the frequency of background checks.

"I have got to assume that all of you are just as tired as I am of seeing this stuff happen in your states. So that's an area where we also need to partner and think about what we can do in a common-sense way, in a bipartisan way, without some of the ideological rhetoric that so often surrounds that issue," he said.

Mr. Obama and the governors also discussed the state-federal relationships in fighting terrorism, the Zika virus, energy issues, trade, and prescription drug abuse.
