Dan joined Parkland shooting survivor David Hogg on CNN’s Reliable Sources for a fascinating interview with Brian Stelter. They covered the attacks on the students (they have even been getting death threats) and March 24’s “March For Our Lives.” Dan told Hogg:

“This march could be a tipping point. This is the first time in years that I have sensed within myself we’re near a tipping point. We’ll see how big the march is and the big thing is do you and the other students have staying power. You have the willpower, but do you have the staying power?”
