PHILADELPHIA — Every couple of minutes, it seems to Daniel Hernandez, someone stops him to ask about gun violence.  

Hernandez is a former intern for Rep. Gabrielle Giffords. He helped save the Arizona Democrat's life after she was shot in the head at a constituent event in 2011.

The event came several days after Obama unveiled a series of executive actions to beef up the federal background check system and other moves intended to curb mass shootings.
