Since an FBI investigation has been ordered for the Ford allegations against Kavanaugh, can Mark Judge/others be forced to testify in person?

Added (1). Judge Judy doesn't read or accept sworn statements because she wants to question them to see how they react to her questioning. Why wouldn't that apply in this case?

They can be subpoenaed

In a non-Stalinist system… Or made-for-TV melodrama… The term is "subpoenaed"…

What does the FBI have to investigate that hasn't already been covered. There are sworn statements from all of the alleged witnesses. There's no evidence. The accuser can't say for sure where or when it happened. It was more than 35 years ago. The FBI has no power to force people to testify.

JUST IN (on my time machine) OFFICIAL FBI REPORT:

Christine Blasey Ford is a wackadoodle liberal nutbag.

CASE CLOSED

No

No. You don't ever have to answer an FBI question, and there are reasons you shouldn't.

No, they don't have to reply at all.

Even if subpoenaed they can sit there for an hour saying I don't remember it was 36 years ago
