I can’t abide the use of the word “vetting” in politics. Stupid. It comes from taking the pet to the vet to see if they are sick, need shots, have all their teeth, etc
Actually, it comes from the word 'veteran'.
It is slang for having a 'veteran' (someone with long term experience and knowledge) evaluate someone new to see if they have the skills to do a job.
And even if it's not, it just sounds better.
