PHILADELPHIA, July 27 (UPI) -- President Barack Obama and Vice President Joe Biden will be the headline speakers in Philadelphia on Wednesday during the third day of the Democratic National Convention which in part will focus on U.S. mass shootings.
Beginning at 4:30 p.m EDT at the Wells Fargo Center in Philadelphia, the DNC's first scheduled speaker will be Erica Smegielski, daughter of Dawn Hochsprung -- the principal of Sandy Hook Elementary who was killed while trying to protect her students. The Sandy Hook, N.J., massacre, which occurred in December 2012, resulted in the deaths of 20 children and six school employees by gunman Adam Lanza. Smegielski has worked as a gun-control advocate since her mother's death.
