MO: it wasn’t a insurrection. It was a rally that was infiltrated with left-wing Trump haters including any cabal on the ‘take’.
Even if it had been an insurrection the 14th Amendment does not apply to ex Presidents.
How could it be an insurrection when the participants had no weapons? Many were only in the vicinity of the building. They had to use cell phone data to find those in the area. That cell phone data, BTW, was provided by Bank of America.
