I doubt much time is spent on this at all. What is there to say really.
You think Lester, Trump or Clinton wants to waste 5-15 minutes out of 90 talking about another shooting when these happen daily, I doubt it.
Trump is going to end the rigged system. Even the current debate is rigged and he still will win. Clintons Former Press Secretary Mike McCurry is the current co chair of the debate and is already pressuring Lester to debate Trump instead of letting them debate each other.
I dunno, I think it might. If for no other reason than the fact it's just one in a string of terror attacks in the last week or so.
I'm not saying it will be a big topic tonight. I wouldn't be surprised if they didn't comment on it until tomorrow.
Though I know Trump likes to stay up late and tweet so who knows.
