Comey’s been a loyal Clinton wallpaper technician for years.
Here’s a link that explains Comey’s action as US Attorney in 2002:

It doesn’t relate to the articles of impeachment against Clinton in 1998, but to an event after.
Comey also kept the Sandy Berger investigation from expanding to include other Clintonistas –

And to add to that Comey’s brother work for a law firm handling Clinton foundation.

I think Comey’s pal Fitzgerald was doing the same with Chicago-area terror charity investigations- preventing them from widening to include the Democrats.
I note they did nab a Republican but strangely they sidestepped the democrats with the same links.
