The background investigation may be re-opened. It's a political decision, not a legal one.
Why? The whole point of a background check is to provide information to the person appointing the subject, and in this case to the committee voting on their nomination.
Since there is no documentation of either of these accusations, a further check would be pointless.
Right. In an ethical administration, the man making the appointment would request the FBI look into Blasey Ford's allegations, including questioning any alleged witnesses.
I know that's out of the question.
How about in an ethical opposition they release any accusations ahead of time instead of waiting until the last minute?
Thou doth protest too much.
Plus these accusations have ZERO credible documentation to them.
I grant you the last-minute nature bringing this forward arouses pushback. It's the nature of sexual assault that it normally occurs in private, and that there is zero documentation absent immediate reporting and a rape kit.
Also, 30+ years later and none of the named witnesses remember anything happening.
And not date, time or location has been given.
What the last minute thing arouses is confirmed assumption of this being nothing more than a political hit job.
