Which is extra ironic given that that is the only form of laughter he himself engages in.
That’s a very valid point.
And to add: I’ve seen some dispute on the bb threads about what damage this invitation did to the NABJ, but nothing about what sort of damage would’ve come from not inviting a major party candidate. IMHO, the Trump camp would’ve used the snub as a campaign talking point. So he still would’ve been the aggrieved party, but we wouldn’t have all the examples of how he should be handled by journalists and the (perhaps redundant) proof that he absolutely can not take it.
