MINNEAPOLIS (AP) -

Mayors, police chiefs and prosecutors from around the Upper Midwest say greater access to data on firearms purchases and strong community partnerships are just a few initiatives that could prevent future gun violence.

The officials are meeting in Minneapolis for a daylong summit on gun policies.

Milwaukee Police Chief Edward Flynn says that while recent mass shootings require federal action, there is also a "slow-motion mass murder" happening in cities across America -- and that daily violence can't be ignored by lawmakers.

Minneapolis Mayor R.T. Rybak says he and others will head to Washington next week to lobby for change to federal gun laws.

Vice President Joe Biden announced Thursday that he has reached a consensus on some proposals, including banning assault weapons, and will present those ideas next week.
