Seems like dude just panicked and came up with something to not make the moment awkward. In that situation he should've just said nothing and said "moving on" of course coli negus who never have been on tv or had media training would've surely called her to crawl back into her cave or would've stood up and roasted her before barking like DMX and walking out Chappelle style. To which the headlines would read "TV anchor goes crazy!" And the white woman is in tears saying she doesnt know what she did and she always suspected he had a temper.
These days when fukkery happens on TV, or is recorded, trust other black people to have your back. Say nothing in the moment that they can spin into you being aggressive and just let the internet do what it does and you'll be taken care of.
If I was him I'd probably say nothing, write a post online explaining my outrage and then I'd take it to H.R. for good measure. If the HR tells me to fukk off, then I'll fire off that post and let the internet take care of it.
