the fBI has a responsibility to do backgrounds on judicial and other nominations,.
Judge Brett Kavanaugh has had 5 or 6 FBI background checks for previous appointments and nothing was found. He surely had a major background check this time also. An FIB investigation of a supposed crime 30 years ago is what I took the democrats to be requesting. A sexual assault classification of a crime nowadays may not have have been a crime 30 years ago anyway I suspect a statute of limitations would have run out.
