I'd give this a listen today. He already mentioned yesterday that a SS source informed him that the security plan called for an agent to be on that roof. I'm sure he'll reveal more today. He's been 12 hours ahead of the news cycle on many key revelations since Saturday.
The cover-up is underway.
I think that it's anything covid is largely avoided. With Trump the most you'll get is reference to how the pandemic wrecked a strong economy. There are other issues where there is wiggle room for independents to listen. Not covid. It's too divisive and there's so much covid fatigue I don't think it's an issue either candidate can win with.
We are in the midst of what can only now be called a DHS/USSS cover up. Delayed hearing, sloped roof, blaming local LE, monitoring shooter for 30 minutes prior, etc.
Thetefore anything suspicious deserves monitoring
