Former President Donald Trump addressed the mass school shooting in Georgia during his Fox News town hall event in a key battleground state, vowing to "heal our world" if he's re-elected. 

"It's a sick and angry world for a lot of reasons and we're going to make it better. We're going to heal our world. We're going to get rid of all these wars that are starting all over the place because of incompetence," Trump said Wednesday from the New Holland Arena in Harrisburg, Pennsylvania. 

Fox News' Sean Hannity, who moderated the town hall, had cited the tragic and fatal shooting that unfolded Wednesday morning in Barrow County, Georgia at a high school, as well as the tight security surrounding Trump's public events following the assassination attempt on his life in July. 

"We're going to hopefully do very well. We have an election coming up … We're going to be, I think, we're going to be very well set up to do a great job," Trump added.
