RICHMOND, Va. — Former Arizona Rep. Gabrielle Giffords has taken her push for tougher gun laws to Virginia and Delaware.

Giffords and her husband, former astronaut Mark Kelly, announced Tuesday at a Richmond news conference the formation of the Virginia Coalition for Common Sense. The group will advocate for legislation aimed at preventing guns from getting into the hands of dangerous people. A top priority will be advocating for mandatory background checks at gun shows.

On Monday, Giffords and Kelly announced the formation of the Delaware Coalition for Common Sense. It hopes to prevent gun sellers from completing a purchase if a background check takes longer than three days.

They recently helped form a similar group in Minnesota.

Giffords was gravely wounded in the 2011 Tucson shooting spree that left six dead and 13 wounded.
