My understanding, from the Senate GOP statement is that it must be limited to existing, credible accusations.

Thanks.

The senate committee addressed a single accusation - Dr. Ford.

their statement used a plural - existing credible accusations

Statement from President @realDonaldTrump:
“I’ve ordered the FBI to conduct a supplemental investigation to update Judge Kavanaugh’s file.
As the Senate has requested, this update must be limited in scope and completed in less than one week.”

so, again, what does limited in scope mean vs. existing credible accusations ?

It should not be that hard to specifically say what to investigate. If anything, Pres. Trump should know the nightmare of a "no specifics" investigation...
